That is an excellent question *laughs* I have wondered that myself. Basically... you put them in your user info, or you can use them as a signature on a forum. The convention is to put "Hermione is LOVE!" underneath, or whatever is love. You can look at my profile for examples. It's all a very silly fandom tradition. Most of those were requests, I don't generally make them. But they are fun to use... I have no idea why ^_^ Thanks for the comment and I'm glad you like them!
