The xperience.php page lists off everyone and you won't necessarily be able to check yourself.
You can search for yourself, assuming that your username is relatively unique. (If for example you registered as "e", good luck! But searching for myself returns just my own row of the table.)
And while I'm posting... I disagree with the idea of counting sheer volume of posts towards anything. Quality over quantity. There are a lot of posts that really don't add anything to the conversation, and thereby detract by just getting in the way.
(I don't
strongly disagree, heatedly or anything like that, I just think ignoring volume would be yield better results (according to what
I personally value, YMMV) and be easier to understand and implement.)
And come to think of it... what happens if someone with negative rep, gives you rep? Does that
lower your rep? And if he gives you negative rep, does that raise your rep? Inquiring minds want to know! ;-)
