[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.
What about adding a drop-down list box to the right of "Vote up | Vote down" etc? Or below that line? The selected message can be displayed in the same space for others to see.
I guess this feature wouldn't be useful for a user who comments on a few threads and then leaves for a week. But there are also extended discussions between regulars here that end without anyone except the author of the parent of the last comment knowing why.
