We now have Facebook, as you can see on the main site. And we now have several domains that all point to the same http://prml.sourceforge.net/ site for now, but will eventually have localized content: http://www.prml.net/ , http://www.prml.mobi/ , http://www.prml.de/ , and http://www.prml.it/ .
And more directly related to the matter of PRML itself, I finally have some of the books needed to make sure PRML is everything it needs to be. While I will be busy reading those for a time, more books are always welcome! See the Amazon wishlist for more.
