send out an email just to let everyone on the mailing list know that we will only ever be sending HUGE updates to that mailing list in-future
and also in that email give them options to join additional mailing lists
-Leaks mailing list, a weekly or bi-weekly mailing list containing some of the best recent leaks to keep those engaged via email in the loop
-governance mailing list, for those interested to be informed of any governance news such as a new IIP being discussed or a new vote been conducted etc.
-and im sure marketing and other community members will come up with another 1 or 2 or few more clever mailing list categories so that we can send more emails on more niche topics to only the right people that are interested...
(slightly separate idea) as Rich points out Council Members could also together write a monthly Blog, this could also be sent out in a Governance mailing list alongside other info to keep the community apprised of Council goings on in the Councils own words regularly
