Is your site almost ready for the general public, but still want some feedback? Or are you using a test/development version of your production site?

Surely you don't want to have everybody looking around, this plugin allows you to configure a group (or more) which members are allowed to access your site. All other members will get a notification (which you can configure) that access is currently limited to the test members.

Especially usefull on test sites which are a copy of a production site is that you can limit the outgoing e-mails to only the members of the test panel group(s).
