I tend to spend time on HF a few times a week, when my brain has more energy than my body. Sometimes, when I am busy on a project I may not contribute anything to the site for a couple of months. Some people become regular and well liked members, then for some reason they just seem to burn out.
I can see that. I have had many times where I needed to strep back for a variety of reasons. Sometimes unexpected things happen but it always makes you worry when they disappear without a word. I hope any and all of your missing friends are well
