Remove links in signatures

[jcr]

I really would like a hack that automatically removes url's in signatures. And / Or a simpler system to edit, change and view all signatures for my users.

I find it really difficult and annoying that I have to search on each and every user to check up their signature, instad of showing them all, in a seperate function, allowing moderators to Edit, delelete and ban the user from having a signature at all.
