Less Wrong is still under construction. Please post any bugs or issues with Less Wrong to this thread. Try to keep each comment thread a clean discussion of each bug or issue.
Requested features... sure, go ahead, but bear in mind we may not be able to implement for a while.

(I feel a little guilty, because I've been up-voting practically every at-least-mediocre top-level post. My first top-level post got upvoted and that gave me the courage to write more of them. At this early point in the site it's more important to encourage good writers to participate than to crack down on posts that aren't perfect.)
