Admin Forum:How to disable all custom signatures on a wiki?

Hello. I'd like to know if there is any way to globally disable all custom signatures on a wiki, so that users get signed with "default" signatures instead. Custom signatures are always a waste of space and brain energy, and make it harder to read the actual posts. We don't currently have a problem with that on a wiki I'm managing, but only due to the majority of users being initially anonymous. Still, it may happen at some point that we start receiving visitors with customized signatures. I consider this a problem. If anybody knows a way to prevent this, please don't hesitate to tell me. Thanks! Mitranim
 * No, this isn't possible - you could set a policy requiring signatures to be plain text, but that might annoy users who edit on other wikis. --  Random Time  11:02, August 19, 2012 (UTC)
