Just as a reminder to all, please feel free to use the report button on the left hand side of a post if you see spam posts. While I (or a Moderator) usually spot spammers threads, it's not so easy to spot a spam post in the middle of a genuine thread. We are currently getting 250 attempted sign ups a day from spammers using automated software! 99% are blocked but a few do get through. I've just changed all the security questions on registration so hopefully it will slow down for a while.
