Hello! Great plugin! But I would like to know if you can add an option for usernames also. My website is available only for registered users and I found a plugin that will add a unique registration code on the register page. So it's really one user, one account. I have users who don't have a static IP address so they basically keep restarting the router or the modem to get a new IP.
Can you add an option next to IP field so you can write the username? So admins will be able to ban users OR both users and IPs.
