how do you label your games that have been analyzed

For example, I want to label the games according to opening

also, what is the easiest way to send a completed game to analysis.  Once a game is over there does not appear to be a button you can press.  Instead, you have to go back to one of the home pages.  This is cumbersome.

thanks

There isn't a facility to tag-ones-games within chess.com. You would have to either export the whole games into an external chess DB - or export the game links and tag those externally.

The only path to request an analysis that I'm aware of is: from the list of finished/archived games, VIEW the game , then click on Computer Analysis. (Of course, if you've made a note of the game number, you could plug this directly into the URL e.g. http://www.chess.com/home/computer_analysis_redirect?id=56136510 - and launch it).
