Upvoting gives the voter one point, downvoting removes one point from the voter. Upvoting gives the target three rep points (it's supposed to be dependent on the voter's rep, but I have failed to observe this, so I guess either this was removed in the design process or no high-rep member has ever upvoted me), and downvoting removes three rep points from the target. More information on the rep system can be found here but may be out of date (did you look at it?). You will have to ask a moderator or a staff member for the correct information I'm afraid - perhaps send them a private message?
I see... so you don't fully know, instead we get to an outdated link. But anyways, I came to the conclusion that we are doing nothing cause the ones that should be here , aren't (yes, the Gamedev.net mods).
I consider my answers helpful, maybe not in the typical way, but they are. I also admit that my hatred for LSU got the best of me on that infamous post, so I apologize for that one. But the others one just baffle me.
And something that everybody failed to answer me is why in the world logging in to the forum means a +1.
Thanks
