Fans: add / remove
This Artist Has 0 Fans

To start it out it can work mutli ways depending on how you wanted to do a module like this. it could be a fan of this artist for drawings artwork or Writers for books but i need it mostly for music...

If you click add it takes the username of the one who clicked it and sends it to the database with the id of the artist.

now if they click remove it would remove that user. from the fans list.
i need it to work with an id. cause i want it to work with my radio so when a song comes up i can throw that info under whats playing and then you can see the fans of each artist...

then i would want to make a standard page that would display the total fans.. Would this be real hard to do ? I aint the best at scripting so i am trying to work little things in here and there but i dont see anything i could use that exists for this...
