Mailing List
We run a mailing list for anyone who wants to subscribe, it is through yahoogroups, seemed like a good idea at the time.

"Our intention is to make this a low volume list with a high signal to noise ratio, therefore you shouldn't receive many emails but those you do receive will contain relevant information, I expect traffic to be in the region of 2-4 mails per month, Mail will be output for the following reasons new or updated products or Vulnerabilities in existing products with the occasional trawl for missing products "
