Migrants to IJ, 2007

I was hoping someone here could help with a problem.

I understood, perhaps wrongly, that someone on LiveJournal could friend an InsaneJournal user's open ID and then, if the IJ user subscribed to the LJ user's feed, she would see friends-locked posts on her IJ friends page.

However, happier_bunny logged into LJ with http://happier_bunny.insanejournal.com as her OpenID identity, and made a comment on a post on my LJ. Then she subscribed to a feed of my LJ, but cannot see my friends locked posts, even though I friended her open ID.

Did we do this wrong?

Should we have used http://happier-bunny.insanejournal.com instead, for instance? Or did we just get the whole process wrong?

Thank you.
