My suggestion, unless this is already planned which I feel it might be, is to have the ability to sign up for an Athion Newsletter thing which would send to your email. It could send every time there's a post on the main website, or any other interesting announcements for the server.
there are 1700ish ppl on a mailchimp mailing list from the old mith and pi forums... I will make a way after launch for a newsletter if needed.
