And so I said that, if they wanted it, I'd put up a post for people to leave comments on. I'd turn back on anonymous commenting, and I'd make it clear that I wasn't going to tolerate any kind of negativity. Asking questions would be ok, telling people that they were in the wrong would not.
So here it is.
I don't want anyone to feel any kind of pressure here. If this fizzles and dies with no comments then I'll survive - but when two friends say that they'd find it useful then who am I to say no?
