He states that this website has 3 objectives: learn Greek from scratch, a daily dose/study, and recommended resources. If you are a student of NTG and do no subscribe to him you should should consider it.
One thing I'm really excited about are his lectures that coincide with Dave Black's wonderful introductory grammar ''Learn to Read New Testament Greek". You have seen me recommend over and over the great work by Bill Mounce "Basics of Biblical Greek". This grammar by Dave Black is also one I recommend without hesitation. His teaching style is fun and keeps you captive while not sacrificing depth. Even if you have gone through another first year grammar, or if you are just beginning, get a copy of Dave's book and follow along with Rob.
You can find his lectures here.
