*Are you going to update the white lion from unknown?
Done. For existing sites, you'll need to modify this yourself manually by going to
Admin > Games, and clicking "Classes"
*Will you continue to update warhammer as we get closer to release with signatures and more content as compared to the content you have available for WoW?
Absolutely. The WoW sigs currently use the WoW Armory, and if the Warhammer devs make something similar, we can definitely build an auto-thinger for it.
*Will you have more templates for War so we all don't look the same?
Of course. We currently only have the one Warhammer layout, but more are on the way.
*Lastly can my guildies upload a signature? (sorry this is a NooB question)
To upload a signature, with your current configuration, they would probably be resigned to uploading the signature to an external image hosting site (such as photobucket or imageshack) then linking to that image (which would be processed as an embedded image). But because you don't currently have the forum system enabled, no one would be able to see it (except on application and news posts).
If, however, you had the Forum
AND the Forum Uploads addon, your users could simply attach a file to a private post (only for themselves) and then reference that newly uploaded file in their signature.
Make sense?
