If I remove a user can he register again with the same e-mail?
If it is a local user, then yes, you can do this and he will be able to register. It is not possible to delete uID users.
And Im having prob with users registering in each og my pages they dont know if they are registered to uid so they try to register and they cant because they are registered to another page from ucoz thats not mine
If they have uID accounts already, they don't need to register on your website, they can use their uID e-mail and password to log in to your website.
