1- The points are used to buy stuff from here
and you get them by posting, by getting ppl to answer your topic and so on (so I'm giving you points right now :P)
2- It has already been said, different patches cannot be in the same game.
3- The easiest way is to create a .txt file in your base folder, type say "whatever yo want to say" in it, rename it to whatever you want.cfg, and then, in the console, bind a key to exec whatever.cfg
Hope that helped.
PS: you could also add taunt below the say line in the cfg if you want to taunt too
