There are some good ideas on the list, but they seem to be having a hard time threading out the good ideas from the bad ones. They could have simply intended to get as many going as they could at first, although the site seems to indicate that they were going to reject/approve each submission on a case by case basis. They also have a thing there about trying to do original proposals that aren't already covered to death, but that hasn't stopped some people (I mean, how many late war German Army ranges do we need on the market these days, anyway?)
I do know that they've had trouble getting items posted. I've had two proposals in for a while (one of them for more than a month), and they haven't posted them yet, and I know I'm not the only one. Not their fault, just more response than I think they expected.
