I too have found myself losing interest in forums that I used to frequent. I have recently gone back to check a couple of them out just to find a ghost town of what used to be a very active forum. When I stopped going there I did not post a reason as to why, I just faded out and stopped posting there. I did receive a warm welcome back by the very few that remembered me and I left a link to my new online home here at TTR.
Dave, I will say that I enjoy reading your posts and hope that you do not get bored and fatigued with us here, but if you do, thank you for the contributions that you have made here.
