UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support html in members signatures for UBB boards?

Check out cgi-bin/ubb_profile.cgi, line 457 and consider adding " || ($key eq 'signature')" right before the ") {".

Note that it's really not recommended to allow HTML in signatures: for example, if the HTML exploit checking rules get stricter, the existing signatures won't follow them.
