Gary Willis have a similar forum called Ask Willis (he will kill you if you call him Gary, only his mother does/did that), either way, he likes updates it four times a year or so, answering a bunch of questions. I think Robben Ford does this, perhaps Scott Henderson too?
Of course it would be cool if Kurt was more active, but I think that if the discussion is intresting enaugh he will jump right into it, but most of the time, we guys/gals often sort things out quite well. Wommusic/ACT is, at least I think so, very active when it comes to handle stuff fast and also answering Kurt related questions.
I dont think this is a board mainly for us communicating with Kurt, but rather with eachother about all and everything, Kurt related or not. I think this forum is about sharing knowledge, and if its made in Kurts name, I just dig it even more.
