I just ran into a strange SQL error on the board software that Shini pointed me towards, and I'm not sure I'll be able to easily pin it down myself. If anyone else runs into an SQL error when editing a post, let me know, specifically one that says "Duplicate entry '[' for key 'post_text'" in the error description. What I do know: it seems to be related to editing a post that contains BBCode. Other than that, I don't really have any details. If anyone else sees anything like this, either post it in this thread with a link to the post that caused it, or IM it to me also with a link.
Edit: Never mind, taken care of now.
