Let's keep this simple and not get bogged down in rules.. yawn. The only 3 things I will specify:
1) Just because you contact someone asking them to read your script doesn't mean they HAVE TO. Similarly, if you don't want to read for someone, be polite - send them an email and tell them, don't ignore them.
2) If they read for you, you have to be prepared to read for them. Remember to say thanks for your feedback too!
3) Never ever be vitriolic, slag someone off or take the mickey out of them, either in the feedback itself or any communication that follows. (If you feel daunted by the prospect of giving measured notes, I recommend sticking to Adrian Mead's idea of ONLY asking questions of the script, as outlined in his "Power of Three" method).
If you find yourself on the receiving end of any of these violations by a reviewer, do let me know.
If you want to use The Feedback Exchange, please leave your details in the comments section of THIS POST. This is just for ease of reference. If you have trouble leaving your details, don't worry: send them to me and I will post them on here. Please don't leave them on my Facebook page or tweet them, as I plan to link this post on the right hand side bar for people to access as and when they need to. (If the comments get very lengthy, I'll make sure there is some kind of "round up"later to make it easier - let's just see what happens, yeah?)
So my recommendations for leaving your details:
REAL NAME - not just your online handle, please. Just put your first name if you prefer
EXPERIENCE - ie. have you ever read any scripts for work placements or internships; are you a member of a site like Zoetrope; any other writing-related stuff of relevance: MAs in screenwriting, competition placings, options, that sort of thing. Don't worry if you have nothing yet, there will be people in the same boat looking for others like you. This doesn't mean less experienced writers *can't* read for more experienced writers and vice versa, however.
INTERESTS - ALL SCRIPTS welcome, including shorts and online drama, etc. However, a couple of things to consider: if you love television and write television scripts, is swapping with people who watch only movies and write feature scripts a good idea? Only you can decide. Similarly, if you have strong preferences on genre and feel unable to deal with scripts of a particular genre you ABSOLUTELY HATE, please be upfront about this. Also, here is a good place to say things you are particularly looking for, ie. crime drama, science fiction, strong female characters, sparkling dialogue, the three acts, the 22 steps, etc.
EMAIL - I suggest using this sort of layout or similar to stop spam bots usernameATemailserviceproviderDOTcom, but please do it any way you like. Links to your own blog or social networking sites are welcome too, but please don't take the mick and advertise your sites, posts etc too much here.
Let's make this a comprehensive list of Bang2writers willing to do peer review! Looking forward to seeing it build up over the coming weeks, months and hopefully - years.
