Can't get correct author posted

I'm getting auto blog to work, but it's showing me (Joe) as the author. Even when I logged in as the blog owner and submitted a post, it still attributed it to me.
Under "Author Details" have it set to use the feed author. The choices if one doesn't exist are only admins, so not sure what to do with that. But, regardless, I've set up author accounts for these blogs in order to make sure the articles are associated with their names.
The featured image isn't transferring either.
I wasn't even sure if this was the best way to make my multisite blogs post on the main site home page. If not, give me a shove and I'll gladly head in the right direction.
