Hi,
Congrats on the new bike! My transition from the mountain bike (aka Cappy) and the new road bike (Quinn) was really, really interesting. In fact, I stupidly tried to take it out the day after I got it while it was raining cats and dogs just because I couldn't wait. Very, very bad idea. Honestly I made the transition by going down to the rail trail and just riding. I did a few laps around the parking lot then took off. The hardest part to get used to for me the brakes. Mountain bikes stop very quickly and I just had to move my fingers to stop. Heh, not so on the road bike. I got REAL familiar with my handle bars and top tube a few times because I forgot to reach for my brakes. Just takes practice. I'm by no means an expert and I have no idea how I'd do in a group (I haven't found one yet). But you'll be surprised how quickly it feels natural. If you're like me though, you might start itching to be able to hop over curbs and other stuff...it's a little difficut to do that on a road bike. I wouldn't recommend it.

Have fun and congrats again!
