I'd also like to know. I can't rep, but this is a really good question. Neutral rep can be very useful.
Don't want to tag any admins or anything. I figure some of the older members here will know.
The person doesn't deserve negative rep, nor positive rep. But you still want to say something about them. Maybe a warning or if you're unsure about them?
Neutral should be enabled. It gives a chance for non upgraded members to rep someone without actually affecting their total rep.
People do check rep and the reasons for rep so if a non upgraded member wants to warn for DWC or to give vouch than they should be able to.
Also one of the rules state that reading the sections already suggested threads is a highly recommended thing to do.
If I had 1 rep for every time this was mentioned I'd have 10,000. @Philly won't bring it back. Also, I think there's a reason too behind why. Can't remember!
1. I think that Onyx should not be able to neg.
2. It would be better then all of these new fags going around dropping neg 5's like they're god.
3. You would still be able to give up to plus 5 but no negs. In my opinion that's better. Then we don't get kids talking shit with their Onyx because they know they can get their rep
massacred.
