No, there is not. That way lies popularity contests of a sort we probably don't want.
If you see a really bad post, please report it to the moderators, if it doesnt' seem to have been dealt with already.
Then how was
Psion able to do that very thing to my account?
As far as I know, he didn't report my post. And, I'm pretty sure there was nothing in my post that was bad, let alone reportable.
I just find it ironic that I recieved positive rep from someone, for a post on the same thread (about a page previously) that was a complete, anabashed, and self-admitted rant. Then, I recieved negative rep for a post that you even agreed with.
Is there a new cadre of forum enforcement, other than moderators, that we didn't know about? It seems to me that some members, other than moderators, are taking it upon themselves to determine what's acceptable and not acceptable for posting.
edit: I would have reported it, but there's no mechanism I can see for reporting negative rep. However, if it's not supposed to be possible to do it, I can understand why there's no mechanism for reporting it. Seems a bit confusing.
