What about a practice?
You know how, when you first post, you don't know how it will turn out and people plead for understanding in the event that their post doesn't quite turn out right? Well, how about a practice thread that's easy to find, where a mod can sort of supervise and advise, members can be helpful, where you can see how to do it before you really post and learn how to put mistakes right and ask questions (like - is this the right place to be submitting this?). A fair bit of this goes on in misc but it's a bit haphazard. Not that I'm knocking haphazard. To be honest I wouldn't mind somewhere for putting a post for a deal together before the real thing and transferring it once it's done.
