Why sticky? lol.
If you want custom client tags, make them yourselves, vote on them, don't vote on them, do whatever you need to do. I've confirmed that I can upload them to the server, so once they're made send them to me all at once and I'll install them. Then it's just a matter of requesting them to be assigned by an admin to tourney winners on an as-needed basis.
If you want a broader application (e.g. based on account age, number of wins/games played) then I'd suggest a stealthbot script that will allow users to self-assign based on an agreed upon set of parameters (e.g. once per month, only certain icons are available to choose from, etc.) Hire a programmer, beg a programmer, program it yourself, I don't really care. If you guys want custom client tags so bad, take some action and make it happen.
