I’m trying to find an answer to this myself. I read something, somewhere that I forgot to bookmark, that basically said this is working as intended. But it seems like massive design flaw. It seems as if it should be able to be fixed, since I CAN see all groups as Admin.
I’ve tried playing with stuff with user access plugins and I can’t find anything to toggle that helps. Assuming it is simply in the theme or plugin somewhere, but I can’t put it together.
You can technically use the External blogs plugin now. I do on a site I run. You just use this for the feed: http://api.twitter.com/1/statuses/user_timeline.rss?screen_name={USERNAME}
