What you should do, since I can mention it now, is get into the wiki and put up your own profile page. It's under community > members. You should be able to figure it out from that point. If you want a stadardized form, there is one on the moderator page under community that you can base your profile on. Then, once you've set up your page, just link that in your sig.

I like to think that, eventually, more people will start doing this. In fact, I think I'll put mine up like that later this morning.
