I tried something different with Photon Courier, as the post updates wouldn't feed. We'll see if David's crossposts at Chicago Boyz fare better. It is a group blog, but I think I've set it correctly so that only his posts hit the sidebar. I haven't figured out how to do that with Texan99's posts at Grim's Hall. Nothing against your co-bloggers, it's just a matter of pedantry.
I dropped Dubbahdee's Neco Dracones, until such time as he starts up again. Just let me know.
Next, I have to check my current commenters for who is also a blogger.
