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.
Javascript is a required browser feature of the site. Its needed for most interaction (as opposed to just clicking around and reading) and to load the side bar.
An FAQ/user guide for the site is needed. In its absence the Reddit help is mostly applicable.
Javascript is only "needed" for basic functionality because that's the way the site has been designed. It could have been designed to degrade gracefully, in which case everything would work perfectly fine without Javascript, with the exception of a few extra page reloads being required.
