I think che does exist on the AAJ board as someone named Andy D.
No shit?
Is he still an active member?
Not sure. I haven't been on that board in a while. But the only reason I make that assumption (and I hereby apologize if I am wrong) is that there probably aren't too many socialist jazz fans from the UK who announce on jazz bulletin boards about their travel plans to Halifax, Canada this summer. Che did that on this board, Andy D did on the AAJ board. Of course, there could be two people making that trip who happen to share similar poltical views and musical tastes, but Halifax just isn't the biggest travel destination so the chances are slim, I'd say.
