There is a site called inktip that sells itself as a destination for writers to get their screenplays read by Bonafide Agents, Producers, Developers, etc. I’ve been a psuedo-member for about a year now, but never bothered to actually e-mail in my signature, because I got the newsletter just the same.
Today, I’ve broken down, my curiosity has got the better of me, and I’ve spent the $60 to have my script listed there for 6 months. It’s not yet posted, but I’ll keep you up to date. I’m curious as to how it works.
