Raph Koster and the Metaplace team are offering yet another round of beta keys for their web-based open platform virtual world. This is a limited use key, according to an announcement on their brand new Facebook page (which you should totally join). Simply visit www.metaplace.com, enter the code "MPWELCOME" into the "redeem your invite key" box, fill out a bit of info about yourself and you're in!

If you're not sure what Metaplace is, you can head over to their website, our tag page, or a recent interview we did with Raph for more information. As Raph says on his own blog, "Quick, hurry!"
