I was meaning to add a post about this issue but Herself shanghaied me into taking her shopping before I'd had time.
So far two forum members have contacted me to say that they've had to complete the affirmation box pictured by Dustydog every time that they want to add a forum post.
The coloured box is anti spam software which has been recently activated to prevent foreign based spammers from robbing us all or corrupting us with lurid offers that would make your hair curl
New membership registrations will need to fill out the box when registering but it shouldn't affect members after that.
A very slight glitch has falsely identified the two forum members as potential spammers, it could be something in the forum usernames or the content of the post which triggers the software.
It's working very well on the real spammers and I've alerted our web technicians about this problem which affects some bona fide forum members. Please bear with us while they work out out to alter things so that errors are minimised.
If anyone else is affected by the software please let us know either via the email link or by adding a post on the forum, the more information that we have the better the software can be fine tuned.
