No, I don't think we can post an explanation of the member level system. That is -- I've never bothered very much with it. Jon Amo, the fella that started up this site, put the member level machine into operation a few years back - but I've not done anything with it. For all I know it might be working dandy or might be broken.
I forget the reasons he started it -- maybe he'll let us know the real story. I don't think it's so we can track the number of posts that each member makes - and reward him with huge monetary gifts for attaining certain milestones.
If Jon A. doesn't offer details -- well, maybe I'll look into the situation and see if I can tell a reasonable story.
Then there are the stars by each person's name. I've got three green ones, you've got one yellow, and folks have up to five of 'em. I dunno this one, either.
Thanks for asking another one of these questions I can't answer. It helps keep my feet in the mud (instead of floating around in the clouds).
