yea mine no longer works and in my profile ive ticked the box telling it to show and there is no "display your sig" tick box... at this rate im seriously thinking about dumping this forum.... had enough of it now.
Yep the "display signatures" option in your forum options is NOT for your sig. It's so you can see others. I've been looking for an admin response for a few weeks, and even sent a feedback e-mail to the TH editorial staff.
Those people are toggled to always include a signature. They couldn't turn it off if they wanted to.
The functionality was removed from the forum interface, but there was once a setting that allowed people to always have a signature. When the control was removed, the setting remained.
