I understand that on SE sites that is a post gets up-voted you get reputation and if it gets down-voted you lose reputation.

On my Area51 SE account I have 41 reputation. I started out with one reputation and then got 50 for giving the site my e-mail which is a feature I guess. I then lost a bunch of reputation from down-votes because I thought example questions were the discussion questions at the top of the proposal page.

I now have 41 reputation on my Area51 account. After realizing my mistake I asked the discussion section Is Area51 Discussions like an SE Meta site? This question has 6 up-votes and I am still at 41 reputation.

Does reputation work different for this site or is this a bug?
