With a heavy heart I have decided to add a captcha test on registrations and comments on this site. The number of spam comments received each day had risen dramatically over the last few months although they were being properly detected by the Akismet plugin. Unfortunately the last few days has seen a meteoric rise in the number of registrations and pretty much all of them were created by automatic bots.
So, from today users will have to complete part of a simple maths sum before either registering or commenting. I have tried to avoid the awful blurred and distorted words which are sometimes just as impossible for humans to read as they are for computers. In the future I may relax the moderation rules so that others can see questions as soon as they are posted rather than waiting for me to approve them. I also hope to continue integrating the forum as a more appropriate place to discuss issues.
