In this tutorial I'm going to explain how to have different signatures that changes everytime you refresh the web. 1. Prepare 2 or more forum signatures and upload them in a image hosting, for example imgur 2.go to http://sig.grumpybumpers.com/ 3.Create and account just puting an username and a password 4.Under "URLs" put in each a direct link to the image 5. Click "Send" 6.Now copy the big link at he top of the web and put it in your forum signature in the same way you put an image. You can see an example refreshing this post, I have 4 different signatures.
