Lockdown provides a simple setting switch for admins to disable or enable new account registration by visitors.
This is experimental code! It's currently used in a couple of nodes in combination with siteaccess. It is to be merged with it at some point.Untested, no warranty, bla, not in preduction, bla, you've been warned. :)
Lockdown offers an on/off setting to allow or disallow users from registering a new account.
It's very early code and wasn't thoroughly tested. Especially the extent of the disable_registration configuration setting remains unknown.
Given away for inspiration and suggestions.
