This news is from maximusdb3 on the Myst Online forums:

The WeeKIly is a Newsletter sent to your KI. I have yet decided as to weather this will be Bi-weekly or "as the events unfold" kind of newsletter though I'll probably start with the later and see how it goes from there. As for now The WeeKIly will only be covering big events taking place in the cavern, though there has been interest in expanding toward neighborhood events down the road.

If you are interested in receiving The WeeKIly you can shoot a KI mail (be sure to put down your KI# within the mail) saying so to Maximus (KI# 88818) or his "associate" WeeKIly Reporter (KI# 1262006). I would prefer that you send to WeeKIly Report as that would be one less step for me, but I'm not picky. If you happen to spot one of us in the city or a hood you can also PM us to be added.
