The pictures in signature may be NO BIGGER than 120 tall by 500 wide.

Multiple signature images are allowed, however, they must add up to 500x120 or lower. For example, you may use a 500x100 image, and also a 500x20 image.

The pictures may not contain flaming, or objectionable content, this is also a temp ban offence.

Signatures containing links to sites which condone live modding, leaks, full .maps files, pornography or any other illegal content are not allowed.

There is no animation signatures at all.

That is about all the rules I can think of.
