A great many first time screenwriters are going to be participating in the 14 Day Screenwriting Contest. ... anyone seeking help over the next two days (today and Friday) for their loglines or titles can post it on my blog. I'm inviting all of you to join in the fun and check in to help people out. ... So log onto my blog and if you see where you can help someone then feel free to pitch in. We want to get folks off on the right foot before they write their first drafts in 14 days (all the time in the world really). The process stops at 7am PST on Saturday.
Sounds like
NaNoWriMo. I would only recommend writing a screenplay in 14 days if you have an outline you've worked all the kinks out of. If you do, 14 days is not an unreasonably short deadline, assuming you don't have both a job
and a family. And writing fast can often get the kinks out of your writing muscles. Anyway, check out Bill's site and feel free to help the guys out.
