I've created an installation of minnow (which will eventually be for production use) at iugo-cafe.org/minnow_pps which includes the newly committed support for access control.

Currently there are two major issues I've found

1 - When you select a name using the drop-down menu, the cursor should automatically jump to the end of the text to allow you to type in the next name.

2 - Need to have some better documentation on how to use the field.
