Signature size rules.
 

I think a Signature Size restriction should be implemented because some users feel they need to have a loud and gaudy signature that could take a long time to load and cause massive lag or other critical system applications to fail on computers with a dial-up or lower connection.

A restriction should be set in pixels to appropriate/standard signature size.

Seconded,

+ Sometimes a huge sig can stretch the forum table layout.

I agree. Sometimes I feel their signature is part of their post (like a pictorial guide on how to hack runescape) but then I realize its just the poster's sig. There is no need to have huge sigs that are 100x larger than your posts.
