I'm in for the Top-100 (Martin, if the list isn't finished then maybe just use your 100 highest rated on Criticker for now?).
One thing to consider about this particular choice for MDC is how personal the lists ought to be... What I mean is this: 'Dumb & Dumber' would figure highly among my personal favorites but even though I love that film dearly I would understand if others maybe didn't hold it in the same regard.
My point is that another variation where we would construct lists for which we tried to settle on 100 Must-Sees or 100 Masterpieces might be an interesting approach.
What I'm suggesting is that we each might seek to weed out (semi-)guilty pleasures in a tricky attempt to constrict the lists to the very "best" films we've seen, based more on originality, execution and whatever other admirable qualities than on personal preferences.
No matter we decide, I think it should be helpful to consider whether this MDC is about dictating films we love or films that we hope others are likely to enjoy (preferably both, obviously!).
Either way, I'm in
