Members lists are currently offline I'm afraid. This is because it's clear that some evil souls have taken it on themselves to use the lists to send unsolicited emails, which doesn't really seem fair does it, bearing in mind we aren't selling anything? This was in spite of obscuring the email addresses to stop them being harvested by programs: so someone's doing it manually.
For more details see [grumpy mail number one] and [grumpy mail number two]. Sorry this is a pain if you're trying to find out if you're subscribed ok. You might want to try [the email search form].
