A little meta-discussion on this website. User permissions are as follows just now (they might get tighter later on):

• 0 points - submit, comment
• 0 points - upvote
• 50 points - downvote costs 1 point
• 100 points - flag costs 1 point

Upvotes on your comments give karma/points to your user, upvotes on submitted stories do not.

Flagging will remove 5 points from story or comment, so use it wisely only on very bad stories. Usually upvote or downvote is fine.

Any suggestions for changes to rules?
