I do think if a submission is given a rating high enough by the mods to put it in the public view, it should stay in the public view no matter how low the rating may go subsequently ... and maybe that is already the case; I don't know.
I've always wondered if that was the way it's set up now.
Since I have it set ip to view all skins, no matter what the rating is, I'm not real worried about what a skin has for a rating. However, if it's too low, it will not show in the gallery for a non-subscriber, and subsequently, will not get as many downloads. It seems to me that that's why most complain about low ratings. (besides the fact that it bruises the ego when something you poured yourself into gets squashed by a moderator
My second idea would be to work on a 50-50 basis which is to say no matter what the moderator has rated it, 7,8,9, for example, it could be rated by the eligible, but could never drop below 5. That would be a knock off point. MIght also help with drive-bys, because if they know they cant rate the skin below 5 then whats the use, just a waste of their time...
So if a moderator rated a skin a 5 then it could not drop below a 4? That sounds reasonable.
