As an experiment, I have turned off registered member-only commenting. Now anyone can comment even if they have not registered. This is made possible by the fact that my blog software has new spam-security features.
This experiment will last as long as spam doesn’t find a way around the security and it isn’t abused by trolls and various other undesirables.
It is still preferable for you to be registered as member of Bettnet so that you don’t have to go through the extra security steps. For the blind or visually impaired, membership will still be necessary because the security feature requires the ability to see an image on the page.
I hope this opens up commenting to a lot more people and generate more interesting comment threads.
