It's been noticed that there are quite a few plots (especially in nerdville) that have been bought but are still empty, and haven't been touched for over a week.
Over the next few days we'll be going through and putting these back up for sale, refunding the current owners. We want thriving towns, so if you've been meaning to build something but have been putting it off, please do so soon! Otherwise you may find that your plot has been bought and built on by someone else!
If you're going away for a while, please post in the AFK thread so we know not to re-appropriate your plots!
