Too bad we can't use external image links in our sigs :( I've got a similar setup running for my guild, therefore I don't use wowreader.

Not that I don't think what you've done is cool, but perhaps you could modify these sigs to be a little less focused on PvP stats for the PvE'ers and include other information such as crafting skills. Just a suggestion.
Anyways, yet another reason to be premium :). Nice work!
EDIT: Forgot to give props. I didn't write the code for that sig display I've got running for my guild. It's included in the roster package available from the WoWProfilers.com community. I just modified it to suit our needs. Just wanted to make that clear so no one accuses me of taking credit for someone else's awesome work. :P
