registering at your casino, just a suggestion might be able to further reduce the parts that must be filled when registering, I think the important thing is that the username, email and password are enough without having to include a surename and name, but all registration went well
During the registration process, you only need to fill out the parts that have the asterisk(*) on them so they only need the username, email, and password which is what you're exactly asking.
The rest like the name, country, etc are just optional though.
