I am sure you did. I can't remember them all, I did so many, but I know that I had to be there 100% for some members because I was proud of their achievements.
One of my favorite was Rink's, the kid was so full of hope and potential that there was no way I was missing it. He had also been the Padawan of a dear friend of mine who shared both Jedi and Knight trials with me.
Other than that, my favorite JK trials were Erue's. He was at the time my best friend in JK2 and one who was there for me when Aoshi was not around.
