You have to install the newest addon for adding new account type

After that it works GREAT
Just what I needed
Only 4 stars because of the not working bundle

The reviewer is correct, this "bundled" version does not work properly except for .0 versions (5.0, 6.0, 7.0). TweeQuilla is an experiment of adding new account types, and though the experiment works, this bundle is not a good idea. I intend instead to upgrade TweeQuilla (app) so that it will automatically install the required New Account Types addon, and abandon this "bundle" version.
