I have bought D7100 for dummies book, my step father printed off a manual for me.......over 300 pages!!!!!!!!!
I will get back to you in 6 months when I have finished reading and understanding it.
Sounds like you've already joined us ... there no more future tense needed.
Congrats! I don't remember which camera body you're coming from, but the plus side with the D7100 is I can always switch it back to full-auto mode if it really comes down to it.
D3200 and now up to the D71
