signatures are like well pictures with designed backgrounds. however on a signature such as mine i have posted quotes and words. basically it's a place to post stuff so long as it is NOT advertisement. take a look at mine for example. notice i have links to my RP and fanclub here on KHI. I also have two sigs which were made by KHI's own forever kingdom. I even have my own DT Great Hall of DTness. which is basically a pointer to some really funny quotes lol.
