Now that the writers' strike is over, scriptwriters can turn their attention to the 10th annual Scriptapalooza contest. The entry fee is $40 to $50 depending on when you submit, and they take e-mail as well as hard copy submissions. There's also a contest for TV scripts. Early bird deadlines are in March, regular deadlines in April. Check them both out if you're interested.
Script writing never held any attraction for me, but I know it does for some people.
