TML Creating Users

Hello

I have installed Theme My Login on my site and a user can be registered with no issue. However, I am also using SP Document Manager to share documents with users and so far I am having to manually add an existing registered user for them to be able to download files from SP. Is there a way that a person can register themselves via TML and automatically can receive files from SP without me having to go to Users->Add Existing user?

Thanks
