These are my rules for affiliation.
Your page has to have to do with Zelda and not have a bunch of other stuff;
Your page has to look good and be well organized (it's always annoying when
you can't find what you want);
No stolen images or anything like that. (Official art doesn't count, unless the
person spent time actually scanning the images).
That's about it, really... That, and an 88x31 mini banner is highly recomended,
but not really required.
