When I am logged in to my multisite network, there is a link under Sites >Add New. When I click on this there is a new site signup form, with no place to type in a password. I've tested it, and it says it creates a username and password automatically and then emails this info. I've noticed it creates a username essentially the same as the subdomain name chosen. I'm okay with that.
However, is there a way (maybe a plugin?) that I can add a password field to the signup form so I can create the password?
