In the interest of expanding the available support options for our users, we’ve created discussion groups (which can be read online, or subscribed to via email or RSS) for all of our products. The main advantage of the discussion groups is that users can speak with other users, which isn’t possible via our existing email or trouble ticket support systems.
We’ve set the groups up via Google Groups, mainly because they’ve got a really good group management system. If you have a Google account, you can sign up for each group via the web, and set your preferences (email delivery, etc.) as you wish. If you don’t have a Google account, you can only sign up via email, and you can’t set any preferences. (This page explains what you can and can’t do in Google Groups if you don’t have a Google account.)
