There is a British Youth Go Mailing List where you can use e-mail to chat about anything to do with Go. Here are some instructions on how to join it.
First go to the Lists page and follow the instructions you find there. There is not so much traffic on this group yet, so you don't need to worry about being swamped with messages.
The moderator of the group has to approve all new subscriptions, to try to ensure that people who want to send spam or other inappropriate messages do not join. Once you have been accepted as a member of the group, you can post to it by sending messages to youth-go at britgo.org (replace "at" by "@").
There will be a few official announcements on the youth Go list too, to remind you of events coming up.
If you have joined the list and want to leave it for any reason, again go to the Lists page and follow the instructions for unsubscribing.
