Very helpful for me and the purpose is exactly what I need because I have a client with unpaid invoices.

Handy simple plugin for diabling an account when you don't want/need to delete the account (i.e a member who has left). This negates the need to delete that users content, comments or to attribute that users comment to another user. (Usage of a users data would be relevant to your site so bear that in mind). For situations where you can disable a user from being able to log into your site, this simply plugin fills that need. A future improvement/suggestion would be to have any messages configurable, or use a language file. Perhaps a 'reason field' so that if a disabled user attempts to log in, not only the disabled message is displayed but an admin configurable message displayed. But those are just nicities... for now, it does what it says on the tin.

Works as intended and perfectly but that's it, there are no parameters or settings to configure. If what it says it does in the description works for you go for it. A shortcode would be helpful as well or any way to programmatically access it, i.e when registering users right from the register code to automatically make the user disabled until it confirms the email account.

You can use this for your site to disable any user from admin access. Thanks
