Okay, here's my proposed structurel:
New films are named on the first day of the month. The designated Filminati member will create a post with the name of the film, as well as any things you want the rest of us to think about and/or watch for while viewing. So Jen, on (or before, since you're the first) March 31, you post your movie choice.
Discussions about the film begin on the last day of the month. Whoever chose the movie creates a new post on the last day of the month to start up and lead the conversation in comments. So Jen, you do that on April 30.
In the meantime, if anyone wants to do a film-related post to spark conversation, by all means do it! Except for when the conversation about the month's movie is rolling along at a good pace, of course. Perhaps the first week of each month should be left to the official movie, but once things die down there, let's fill the space.
If you see any serious flaws in this plan, please don't hesitate to point them out to me. No, not flaws in me, flaws in the plan.
So the big question is, who wants to do next month? First one to say, "Me! Me! Oh, please pick me!" in the comment to this post goes next.
