The new Halo Babies site was made possible by donations from the shadow government... I mean, from loyal fans of the comic. The site has now opened a special area dedicated to them in the forum.

The Sponsors area is described as being similar to Red vs. Blue's; it will feature new comics a bit earlier than the general release. Right now, they're running a contest; a $10 donation or more between now and April gets you access to the Sponsors area, plus a chance to be drawn into a future Halo Babies comic.

NOTE: As of right now, the link from the post at Halo Babies just goes to the general forum; I can't see any special sponsor area yet. I thought at first it was because I wasn't logged in, but now that I have, I still don't see anything.

UPDATE: mrsmiley informed me that I couldn't see the Sponsors area because it was hidden from anyone not a sponsor. Now it displays for everybody, although only sponsors have access to it. I've seen it, and it is cool :)
