There is currently an issue with one of our database servers. It is causing problems with submissions and edits not appearing, and also is causing forums posts to not appear sometimes. We are dealing with this issue right now, it is advisable not to submit until we get it running again. This may be affecting other parts of the site as well.
Update 11:30am PDT: This issue has been solved. There was no data loss and everything is back to normal. ~Kevin
