@Igor My proposal is to keep the paywall but let people see the content of the website for free. Currently everything is behind closed doors, no one can see what exactly we are doing here.
Only those who want to comment or post a topic should have to pay a membership.
This way we keep unwanted firestarters and trolls away. I don't think there would be someone willing to pay just to have the ability to rant for anything.
You will also have a worthy revenue because more people will be willing to pay the small annual subscription just to post their question having seen the quality of help in this site.
