You still have your devices here and, with them, texting access—even with the living. However, it seems like the living side won't be getting your messages instantly, oh no! Signal gets wonky across long distances... you know how it is... Still, at least you can keep in touch.
You may also send physical objects over to the living, via dropping them off in Storage/Lost Claims, labeled with the intended "owner" (recipient). They will be delivered according to the airport's schedule.
Use the appropriate weekly header & outgoing mail sub-header and fill out the form to send some mail to the living! Incoming mail for your characters will also be posted here under its own sub-header.
Week 0 Note: The graveyard-exclusive characters who arrived here via bus do not yet have access to message the living and therefore cannot send mail at this time. They will be notified when they have access.
Please refer to the comment below for any additional rules for sending your mail.
