rename function on the forum

Dear GM! i start play game Crossfire in 2010 year in Russian server. In 2012 or 2013 russian players say me about Crossfire NA (in Russian sleng Canadka). And i register on this server, and i start play, and look on shop, weapons black markcet, events. and online..... when registering, I thought that I would come back for a short time, since there will be a big ping, restriction of IP.
I entered the forum name just a set of letters ... now when I play here more than on the Russian server, I need to sit on the forum, create themes in order to make the game better, etc. .. my set of letters is very annoying, do this function for peoples like me.
