I tried unsubscribing from your emails this morning through the unsubscribe link at the bottom of your email. I don't read them as it's easier for me to keep up with what's going on through Google Reader.
When I deselected all the tickboxes and hit enter it complained that there was something wrong with my email address so I double checked and all was fine. I tried and again without success and then went back to the subscribe page and re-selected one of the options, clicked ok and it was fine.
Can you look into this? It is the same address as my forum account or I can PM if needs be.
