I used to be able to upvote/downvote, but it stopped working in the past few months.
Yeah, that's probably it. I changed the number of posts required to be able to vote. It used to be low, like 10 or 20. Now it's closer to a century...
Just keep posting, and you'll get there.
I'm trying to discourage trolls *cough* CROIX DE FER *cough* from signing up again and again, and downvoting people before being banned.
If it takes 100 posts, he'll probably out himself/cross the line/etc. before he ever gets to 100 -- then it's back to square one!
