Batch Create doesn't work?

Using the standard wp mu 2.7.2, 2.9.2, and 3.0, and a standard BP install with standard BP theme... the batch create users does not work. It will go through the loop of creating the user (and it even says it created them successfully) however the users are certainly not created when I check the mySQL.

Any insights?

NVM, imports them to the WPMU users. Im a tard for that one.
