Got a couple of bugs / suggestions to report.
1) On the forum edit profile page, Signature appears twice, imput into the first box isn't saved and not sure why it appears - it does regardless of whether the bbcode/html enhancement setting is active. Screenshot: http://i.imgur.com/qfNjW.jpg
2) The signature appears at the VERY bottom of posts under edit revision logs - should probaly be above; directly under the post content. Screenshot: http://i.imgur.com/ZNeGv.jpg
3) The forum signature text area ignores line breaks, forcing the whole signature to be on one line - why?! Bug or feature?
4) If it's not viable to have bbcode / html buttons above edit signature box, can there be a bit of text that says "BBCode: Enabled" and maybe with a link to a list of allowed tags.
