Okay, I've gone into me.com and created an album in the photo app. I've checked the buttons that say "allow posting from email or iPhone". I can see the album in the public gallery. But when I try to send a photo to it from my iPhone in the Photos app, it says "Your MobileMe Gallery has no shared albums. Publish an album using iPhoto '08 and select "Adding of photos via email". I don't have iPhoto because I'm not a Mac user. Is this feature restricted to just Mac users? I sure hope not.
