I've received a belated e-mail response. He viewed my profile at 7:43 p.m. Friday. And he responded at 5:07 p.m. today. Oh, and he's 6'5".
O frabjous day! Callooh, callay!
So, one response out of six (I, uh, sent out a couple more e-mails last night)...that's...well, it's better than nothing, in any case. And the old self-esteem meter creeps back up just a smidgen.
