Of course I am claiming bigest NMA fan status. I started this thread and said it will be a friendly competition: who is the biggest NMA fan here? I gave three reasons why it is me. So far no one has given reasons why they should take away my crown.
And remember, folks, it's a friendly competition. No one's feelings are to be hurt here. Just a fun exercise.

No doubt my favorite band is The Beatles, but in no way would I claim to be the biggest fan on Earth of theirs. Yes, I have a ton of the same guitars they used, but no I never had to buy a Region free DVD player in order to watch their videos, and, no, I never co-wrote any tunes with Lennon or McCartney.
No, I'm not "The Biggest Beatles Fan" on Earth, but I clearly am "The Biggest New Model Army" fan.
