Sorry for the short thread, and I'm not sure if it should be here, but I figured Off-Topic seems slightly appropriate. I can't seem to find edit signature on 'settings'. Any help? Thank you.
We don't allow threads just to ask questions like this so gonna have to close it.
The button you're looking for is to the left side of settings, in the third box down titled "my settings" there will be Edit profile, Edit Avatar, Edit Signature and Profile Privacy.
In the future if you have any questions like this, feel free to PM any online mod with it instead of making a thread for it
