A Huge Fan or Big Fan how to prove it?

[cybermoomba]

I think if you own at least 1 CD then you're a fan

I think a big fan would be someone that owns all the CDs/DVDs, attends concerts, is up-to-date with the artist, tells others about the artist.

A huge fan would be some that owns all the CDs/DVDs, attends every concert, knows everything about the artist, owns every single piece of merchandise ever released, tries to convert random people into fans.
