Thanks for alerting us to the spam problem- the sneaky method used was a seemingly genuine forum contribution that was then used to send spam as comments on your individual forum entries. As we do not always catch every comment submitted, and the original request for a password seemed valid, this spammer was given access. It helped a great deal that a forum entry brought the problem to our attention once again. Our webmaster has deleted their access for now but please do let us know when/if it should happen again. As they are persistent, we must be as well.
