Time saver. One problem I have. I wanted to bulk load 1,200 users and have their Group assigned to - Registered. This application defaults the group to - Author. So now that I have over 1,200 users assigned as Author I have to one-by-one assign them to Registered. This needed extension could be greatly improved if you allow the import file (csv) to specify the group on at item by item basis.
(As already resolved via the tracker forum)
This probably means you're usually not logged in as a super amdin, which is a practice to be applauded. When you log in as a super admin, you can change various parameters. You'll want to change the second option (User type).
