XDA Support Threads
The XDA support threads are hands down the best (and my most preffered) way for you to contact me about a technical issue, the main reason being – the Tapatalk forum app is great on mobile and makes it really easy for me to respond to stuff on the go. Here are all the threads dedicated to NRT:
Wug’s Nexus Root Toolkit – Nexus 7 Thread (Also the main/universal thread)
Sidenote: XDA requires new users to post at least 10 things before they can post in a developer thread; I know this is a little annoying – but I prefer that you go ahead and do this (and get it over with) rather than PM me directly. I much rather respond to a post publicly than via PM because the answer I provide may also might help others.
I also strongly advise searching the threads first for your question – there is a good chance that I or some else already answered it.
