I do believe fb only lets you have 1 acct to an email address. You might try a different email on your computer and see. Otherwise you are stuck with the one you created, but can go back and edit the name and change it to a name that the "group" would use. You would be in charge as if it was your own, and then set it as private for just them. Then as they find others they can let you know and you can send invites for more friends as the group sees fit. Unless recent changes have made some new deal possible,,thats how I would do it.
