According to the Beta forums, the Beta is no more and this is the site design (though bugs will be fixed and there will likely continue to be changes), so no reverting to the old format.
I can't speak to the iPad app, but when you click on a person's name on a full browser you go to a page with 3 tabs:
The About Me tab has that information.
This morning I woke up to a, or the, beta version which displays things in a much different way. I like some of the changes a lot, such as displaying the boards for current on-line games, but there are some things which I can't find, such as the screen which gives the plyer's name, birthday, etc. I'm using an iPad app, btw.
My questions are, am I stuck with this version now or can I revert to the former layout, and can I still get to a home page (and if so, how).
