Holy moly, I have received a flurry of responses to my "reminder" PM. Here's where it stands:

D. Wolf* - your print is in the works, your Secret Santa apologizes
Akki14 - no communication from your Secret Santa yet
astroclimb* - your print was sent June 23, did you get your print?
KWhitmore - no communication from your Secret Santa either
gphoto120 - no communication from your Secret Santa
mikeg - your Secret Santa made your print and will get it to you soon
vet173 - your Secret Santa made your print and will get it to you soon
CPorter* - did you get your print?
jgcull* - your Secret Santa swears he sent a print and I am "investigating his claim"
jbannow* - did you get your print?

OK, we'll give this a couple more weeks to sort out, before I start naming names. Also, because I have extensive travels in a couple weeks, so I'll be an absentee organizer.
