i think it can be used effectively in some cases, but it's definitely not being done here.
I'll agree with this and what Broken said. When used properly, it's a great indication to newer members as to who is a credible source of information versus just random advice and nothing to back it. IMO, the rep. system has been abused a lot on Club Integra, so it's a little hard to tell who has earned it by being helpful and giving solid advice versus who has gained it because they've picked on someone else and other people found it funny.
The only members who really know are the ones who've actually been around a while and have learned who can help you out when you need it. That's how I learned. So...normally I don't care either way, but in this case, I think a few people have ruined it for the rest of the site. It sucks, but it probably would be better removed. lol Less tears will be shed...
