Hi,
in my opinion, access should not be given for money nor by invitation.
As there are many assholes on this planet who only grap information and you never get something back but a kick in your ass, or even bigger assholes who tell everybody your stories they meet at the baker, it would be nice if there could be an area for people who are willing to share information.
How to check someones intention? I do not know.
Best regards, Rainer
