I want the site to remain online with all user data in place, but I don't want anyone (other than the administrators) to be able to log in.
Is there a way I can prevent a set of users from actually logging in to their accounts without doing any development?
I'm thinking I might have to write a small plugin to disable logging in for anyone other than the admin usergroup - but was hoping there was a nicer way to achieve the same thing without programming.
Anyone have any suggestions on what else I should consider doing as part of the archival process?
I had considered replacing all of the user passwords just in case - but I'll also need to ensure that nobody is able to reset them using the password reset facilities.
Anything else I should consider?
