How do I know my coach is qualified?

[TheWorstPlayer]

I started coaching not that very long after I started getting coached, actually. I was both coaching and getting coached for a long time. I started getting coached on NL25 at Party by BK_ (note the underscore!) in 2004. I then started coaching probably around 2005 and have been coaching ever since. I may have coached 50 students by now. Definitely 30. Many of whom are now better players than I am (although maybe not on a theoretical basis!)
