As far as I understand it's not possible to fore a user to update their signature? Or is there a way to force them? I have an old user that still has 3 links in her signature, we only allow 1 link in the signature now. I would like to reduce that to 1, but I don't like to edit their signature. I can ask of course, but it would be nice if we could force them to update the signature at the next login or so.
