I frequent several internet forums and have noticed that I tend to take breaks from posting on all of them from time to time. I still frequent them, but for some reason I go into lurk mode on occasion. I think it is fairly normal on a recovery forum to fear the worst when a regular doesn't post for awhile. I know I have the same worries if someone in my AA home group is absent several weeks in a row.
Having said that, I think an occasional "shout out" is in order from anyone that has been MIA lately.
