Yep. I have hit it a few times, not really recently. But anytime there is a big in depth discussion, it all just comes to a halt when you or other active posters use up their 20 posts. Gotta wait 24 hours to have discussion again, and by then it's kind of died down. I don't really get the post limit, or rather I don't get why it's so low if there is going to be one.
