What is SigRotor?
SigRotor is a free signature rotation service for use on forums.
Huh?
Essentially, SigRotor allows you to build a rota from which a random image is selected each time someone views your signature on a forum, meaning you can have dynamic signatures which are different each time they are viewed.
Please note that SigRotor is currently only available for use on the Overclockers UK forums (you can try it elsewhere but it won't work). This will hopefully be extended to other forums in the future once I've tested the demand on the service.
