My second time posting in this thread, hopefully it's alright!
I was just wondering when you're going to open the 'guest forum' once again? We have lots of guests in here, and some of them probably know more than we do. Maybe they've new information to share but they can't register? And in everything, they can't discuss their registration problems due to this.
My suggestion is, that you open the forum for some time and see what happens. If the same happens, don't even bother opening it again sometime soon.
Hopefully my opinion will be heard by you, Souza.
Blessings.
