I know some people have been encountering occasional database errors. While these are mostly likely a result of the high volume of traffic that visits this forum during peak hours (US evening/weekends), I'm hoping to confirm just in case there's a fixable error at work.
Please post any database errors that you encounter.
If the database error reads anything like "too many connections" or "max connections" then it's likely just the forums being too busy, you can usually just go back and try again if you were posting a message. If you do re-try an attempt to post a message, then please remember to check that your first attempt didn't actually go through, otherwise you might end up double-posting!
