[Edit: Issues, Bugs, and Requested Features should be tracked at Google Code, not here -- matt, 2010-04-23]
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.
The link and comment score thresholds in the Preferences menu give the impression that by leaving them blank, all articles and comments will be shown regardless of their score.
If left blank, the preferences can't seem to be saved, and they appear to revert to zero: nothing with a score lower than zero shows.
I'm not having this problem - I set them to blank and saved successfully, and can see negative-score comments.
