Over the next 2 days, there will be multiple upgrades to both the server software, as well as the forums.
The server technicians will be performing the server upgrades any time (I'm not sure when). I will be upgrading the forums on May 30th (sometime in the evening).
There may be some site downtime involved, but it should not be for very long.
These upgrades will help the site stay secure and fast for your enjoyment!
