I guess it's strange, but telephoning only occurred to me as a last-ditch emergency strategy, following attempts at email (primary), IM/chat (secondary), and then finally posting a general notice on LJ. Probably because I only check voicemail a few times per week, myself.

If this LJ post hadn't worked, I might have then tried to look up numbers... I had a couple, actually, I probably could have gotten someone at the main Dreamland house number to relay a message (several people there currently have dead cellphones). Thanks for the suggestion, I should try to call before trying LJ next time...
