Hi there, and welcome. I'm also fairly new to this site, but, I really dig it, as I'm sure you will also.
I have been a commuter in the past... two different times, once 38 miles round trip, and once 27 mile round trip. Both times were on road bikes. If I had the chance, I'd do it again. So, I relate to where you are in the cycling world... I began serious cycling in the mid 70's, and I'm learning new stuff every time I log on.
As you have already experienced... the people on this forum are helpful, humorous, and understanding.

ENJOY...:thumbup:

using the "get more" feature with the smiles, is one of my favorites...:fun: :fun:
