After a discussion about reputation systems happened on #norkdot, with Espadon being one of the main supporters of the idea, I took the matter to our moderators. We had a long, heated argument about it, but in the end we decided that we have a strong enough poster base to make good use of it. Zulu is centered around goodposting after all.
Some of you may dislike the system, my suggestion to you is to simply ignore it. I'll even look into disabling it visually for those who don't want it. At the moment I believe rep bars are not visible; I'm looking into it.
For the rest of us, go forth and upvote!
