I'm done making the registration page friendly by removing the unnecessary fields. Also I have a recommendation. I think we can enable the facebook integration :) so user can use their facebook account for logging in the forum which make them easier :)

I confirm facebook integration

I created a separate thread for this task.

This simplified form of registration will be preserved when updating the forum version or will it have to be restored?

It will be preserved :) but if we will change a new theme we need to copy the changes on the new theme.
