Answered Signature markup on new forums?

Signatures support a limited subset of bbcode, not including tables or images. Links, bold, italics, color, quotes, underline, and probably a few others are supported. We're trying to keep forum signatures a lot more clean than they have been in the past.

We'll fully document the allowed signature bbcode elements when we update the profile page, but first we have to fix a few other profile-saving problems (birthdays, github accounts…). We wanted to get those done for the re-launch, but we fell back to iterating more often in order to ship a ton of other improvements sooner.
