You are not alone... many of the regular members have cut back on "forum time" over the last year.
Many folks have had a lot going on at the same time and forum traffic has slowed some. I have noticed that a good many regulars still visit, but posting comments has slowed.
I myself have kept up with postings (logging in to stay current), but due to being busy with a wide variety of things from church to family health issues, I have cut way back on commenting.
Anyway, good to see you back, Andy.
(and here's hoping that more folks can get back to posting great discussions)
