The Power of Online Mailing List
There are many interactive mailing list out there and one of the common ones I use is YahooGroups. They work great, just create a group of join a group to participate and groups are usually about a topic an nearly any kind of topic can be found in the YahooGroups. When set up, you just have one email address to send to when you need to email anyone in the group and all recipients can simply reply to that email and everyone will receive it too. It runs more convienient than the traditional NNTP
To get more Informatics Students and even Alumni, I searched for some YahooGroups on Informatics Schools worldwide and will invite them to interact and share in the forums.
