I don't know where to ask this one. I want to ask where can I set my signature. I thought that's in my User CP under Settings & Options, but ... see picture.
Is there a restriction? For example: only S1/S2 users can have sigs?

Demo racers cannot set their avatars and signatures.

Thanks for the fast reply! (You can delete the thread, if you want)

Yup.

Only S1/S2 users can have signature and avatars.

The reason is that otherwise someone could make spamaccounts with disturbing avatars and links to viruses in their signatures.

There are, however, some demo-users who have avatars/signatures, this is because 9(?) years ago, demo-users could have avatars and signatures. They didn't (try to) change it, so they still have their av/sig.
