So basically, you want a "GT member" sprite. Should only other GT members see it, or everyone? Can you give me the exact color code included characters for [GT] - so I can make it work depending on such nicknames?
Should it also show [GT] members of other teams?
Actually... I think I am going to do it a bit differently... maybe I should make a (toggleable) special sprite for members of the same clan in the same team, defined by a list of nickname prefixes/suffixes in a config file on the server? It would only work in team matches, and maybe not using nickname prefix/suffix, but a client cvar for a clan "ID"... not sure yet.
