[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.
This behaviour is something that we can configure in the editor. I've raised an issue for it.
Eliezer. We've changed the editor configuration to not generate relative paths. It will still generate ones relative to the site root though, which is desired behaviour. E.g. If you paste a link to http://lesswrong.com/lw/5/issues_bugs_and_requested_features/78 it will save it as /lw/5/issues_bugs_and_requested_features/78 which will work no matter where you are on the site.
