Cool
4-Player Chess Wikibook
Nice start. This will be very helpful.
Very nice 
I have created a 4pc diagram template, so now diagrams can easily be added to the Wikibook to show positions.
Nice
Please add that "Stalemate is a Draw." in Teams. We added this phrase to the Rules in yesterday's release.
That was already in there actually.
To reiterate, the point of Wikibooks is that everyone can edit or contribute things. So, please, feel free to do so. The book won't write itself. Each page also has a discussion page associated with it. So, if you want to make a change or add something and you're not sure how to go about it, you can always start a discussion with others to exchange opinions and ideas.
I wrote quite a bit on the scandinavian, and also added some diagrams. Are they supposed to be added somewhere else? They all get lined up on the right, maybe you can check the formatting.
See the diagram template documentation. (And have a look at the Conventions as well.)
You can choose between tright or tleft for the alignment or leave it out. I think it's better to use the large diagram only for the current position at the top and to use smaller diagrams (add size = 20) in the rest of the text when discussing positions that may be reached later, since the large diagrams take up quite some space. (You can also leave out the file and rank labels on one or both sides of the board with numbers = left, right, both or neither and letters = top, bottom, both or neither.)
Also, update the FEN4 of the position shown, if you include it in the diagram, or just leave it out. Common moves are just for quick navigation from the current position, so you don't have to include that in diagrams that show other positions.
To clarify, the idea is that each move will have its own subpage (like a directory) and each page covers the ideas in that particular position. You can highlight ideas using longer lines and show variations that may result from a particular move, like you did, but note that each move in those lines will also have its own dedicated subpage for more elaborate discussion of that particular position.
For example, the page /1._h3/1...c7 is for discussing the ideas behind the move c7, give an overview of the main replies and mention any key lines or openings that may be reached from that position with a link to refer to the pages where those lines and openings are discussed in detail. So, then the page /1._h3/1...c7/1...h12 is for discussing the main ideas behind h12 and the main replies and similarly /1._h3/1...c7/1...h12/1...l9 is dedicated to the position after the move 1...l9 etc.
On the page for c7 (/1._h3/1...c7) you can then mention how c7 may lead to, e.g. the Icystun-Rezacz Defence later on and link to the page /1._h3/1...c7/1...h12/1...l10, where the Icystun-Rezacz Defence is then described in more detail.
I need to know where to place the alignment, it probably says in the "documentation" but I had enough and just copied what I needed 
. To create a new page you just write that command and they will ask if you want to create a new page or?
Just replace the tright by tleft (first line after the title). To create a new page, you simply create the link and it will show up red in the text, saying the page doesn't exist. Then you click the link to create the page.
Ok. Do you feel like Nimzowitsch defense is appropriate for 1. Nl9? I called it Valger's defense, maybe it can have dual names?
Yeah, what I did so far is just name the openings using a combination of regular chess opening names. And if teammates open the same way, I called it "Classical" and otherwise "Modern". For example, I called 1. h3 d6 h12 Nl9 the "Modern Sicilian, Nimzowitsch Variation". So, if you want to follow that system, then Nl9 would indeed be a Nimzowitsch Variation.
Perhaps we can use that as a sort of "official" naming system and in addition to that mention that the opening is "also commonly known as" e.g. Valger's Defence.
Nice, good job!
Please feel free to use my ' WTA strategy guide' as if it was your own and add it to the wikibook, modify the wording, etc.
I also have piece of constructive crticism: I looked at the book and the pages were looking super nice, but I found they lacked a lot of hyperlinks. for instance, on the main 4PC page, you have a section about FFA and a section about Teams variant. But both arent hyperlinked. It would be important to have as many hyperlinks as possible in order to facilitate navigation through the book.
@Bill13Cooper Everyone can contribute, so if you want to add your WTA strategy guide, feel free to do so.
Regarding the links, do you mean the strategy page? There is a table of contents on each page linking to all the sections. I'm not sure what you mean.
Where did the section with valger's defense go? I suddenly can't see it.
Sure, but I thought there was a diagram with it too? Pretty sure I had put it in there...
What do you mean? The diagram is right next to it. Nothing was removed.
Some time ago I proposed the idea to create a Wikibook for 4-player chess, covering the rules, tactics and strategies and documenting the "opening theory" (for the Teams variant). I have now actually started a Wikibook, which can be found here, and everyone who is willing to contribute to it, can do so. The idea is to create something similar to the existing Wikibooks for regular chess (see Chess, Chess Opening Theory, Chess Strategy).
If you do plan to contribute to it, get familiar with Wikibooks first and make sure you do not violate any Wikibooks policies, to avoid getting blocked or having pages deleted. Wikibooks pages are continuously monitored by automated filters and by administrators to prevent vandalism and spam / advertisement. It's best to avoid including external links, unless absolutely necessary and justifiable. (I found out the hard way and got blocked immediately after referring to chess.com.
