Thanks for all the well wishes! As I read your responses, so many things popped into my mind -- I feel like I could have a conversation with each of you.
BleeckerSt_Girl -- I've been meaning to tell you - your Luna is a mighty sharp bike! Hopefully you've been able to put many happy miles on her.
dachshund -- hey, I see you're getting a Seven from Chris Robinson. Have you spec'd it out? When's the delivery date?
smilingcat -- a Litespeed is certainly no slouch. I haven't had the chance to ride the Merlin after the test ride, but luscious is a great description for its ride and looks.
sundial -- I can't tell you how extremely fortunate I feel to have found this bike. Found it on craigslist. I rarely find a bike in my size (thank God, or I'd have a gazillion bikes). This bike was the right size, right material, and the seller was within walking distance of my workplace. It was pretty much meant to be.
KnottedYet -- I hear congratulations are in order to you & Trek!
Bad JuJu -- Delicious indeed! And luscious too!!
jesvetmed -- alas, no pics yet. Soon!
madscot13 -- Good job on building up your bike -- I see that you picked out some mighty fine components and hope you're enjoying your steed.
aka_kim -- welcome back from Colorado you slacker. 
ilima -- what kind of Merlin do you have?
SadieKate -- The seat stays are shaped exactly like the ones in the picture you attached. Well, except they're a lot shorter. And they're a combo of ti and carbon. And there's a little bit of engraving right where the ti meets the carbon. But that pic! OMG - I want *that* bike too!
Oh, and tell Bubba that he can borrow my Merlin any time. He can fit on an XS frame, right? 
indysteel -- sounds like you might be getting a Spectrum build. I'll watch for it right here on TE.
Ann G & KatyLady -- Pics and ride reports coming soon. (Work permitting.)
- Melissa
I'll get back on the bike soon, I promise!
