I'm having similar difficulties.  I have a site in which I want to show a roktabs module containing report articles to a specific registered user.  User1 gets to see the module with his reports, user2 gets to see only his reports, and unlogged users see some standard text.

I have been using the single user recipe - but there are two problems:
1)If user1 logs in, user1 can see his module, but so can anyone else who goes to the site when user1 is logged in.
2)I'm also having problems modifying the code so that metamod can identify a single user from multiple users and return only the module specific to that individual, as in the logic "if user1, show user1 reports, else if user2, show user2 reports."

Any help would be much appreciated.
Thanks,
Andrew

Yep, you got it :-)
