I've added signature support to the forum. You can edit your signature by clicking the gear icon on the top right, choosing Edit Profile, the Signature Settings on the right middle. The idea is that you can put your PC specs in there, or a link to your website, etc. just keep it reasonable. Cheers.
I wish there were a preference setting so you could hide them. Reason: I sometimes use TTS to listen to long threads and it insists on reading every single signature. 😞
