I come bearing gifts with spread arms and legs! Don't be filthy, it's an innocent gesture.
New private messaging system
You can now send PMs to Dtoiders that don't have forum accounts. You'll spot the new PM buttons next to the comments of a user or on the new top-right section of their cblogs. You can also send them with a challenge to play a game, which sends a special type of PM with suggested timestamps and an RSVP link. Outbound PMs appear in the new "inbox" link at the top of the page and the person you PM'd gets an email as well.
New Cblog layout
Notice the buttons on the top right of my blog header? How about the new tabs below, like the "my comments" one? You can now stalk each other more easily. Enjoy!
