Hi I just provided your team access via my WPMU Dev dashboard. There is a question about using the autoblog on a specific subdomain, and I left the details there. You will find the login for the subdomain there.
The feed doesn't seem to be adding anything to the blog, and it is a valid feed. I also tried turning on some of the add ons but had no success. Can you let me know if it's simply not compatible or something else? Thanks!
