WilLoW :--) would definitely be the person to try and contact about it since it was his brainchild. He hasn't logged in for quite a while though so it may be difficult to get ahold of him.
This was one of the last posts on this forum by WilLoW :--) involving the AniMix. He was talking about an AniMix 2 and shared some history on the original project.
When it comes to members who worked on the project and are still active....
AMV_4000 - Shows up here and there
AquaSky - Can occasionally be found in #AMV, the irc channel
Hitori - Just saw him at AX this July and he said he's currently on a mission to help MEPs that have been going on forever finally finish.
Ingow - I see him every once in a while on Facebook so he's alive?

JCD - Still an active editor, not so much on the forums though.
Pwolf - Still a very active member on the forums and easy to get in touch with.
SarahtheBoring - She makes new videos from time to time, but not really ever on the forums.
Sephiroth - Really only shows up for the Anime Expo contest thread, beyond that, not active in the community.
And now for a bit of self-pimping

I'm a HUGE fan (I have the entire thing memorized by heart...yeah, I have a problem..) of the AniMix too. So much so that I'm putting together an MEP dedicated to it and the 10 year anniversary of the finished project!
