First, I'm glad the lessons helped you.

Yes, anyone can post lessons here.
As to who I am...
It's no secret

I'm just a regular guy. I'm not a moderator or anything other than a long time forum member (going on 5 years now). I'm a 22 year old college student. In my spare time I try to help people out with their music theory questions. By no means am I an expert.
I've been
playing guitar for 14 years. My music can be heard here:
