This is the wrong place to ask about forum-related questions like signatures. You ask questions like that in the [url-inline=forumdisplay.php?f=4]Community Questions and Feedback[/url-inline] section, not Pokemon General. ._.; Just remember that next time. =)
[url-inline=forumdisplay.php?f=62]It's called the Trainer Card section. =D[/url-inline]
In there, you'll find nice shops. They'll make trainer cards how you want them. All you have to do is ask and follow the rules of their shop, that's all. ^^
If you want to learn how to make one, look at the [url-inline=showthread.php?t=14980]FAQ.[/url-inline] You insert it in your sig how you do an image.
However, I wouldn't put one in your sig at the moment. It's already over the size limit as it is. You need to put one of those animations on another line -- you're breaking the width limit. @@
Anyway, the question is answered, and it doesn't follow the rules in CQ&F or Trainer Cards, so...
