I still like to keep an eye on new members and the count. Back when, I had an IT guy helping me run this site and he told me I should purge anyone who had not logged in for a long time, say 2 years. He scared me with stories of hidden viruses that would set off after a given time, so I followed his advice and began deleting uses who no longer logged in after 2 years.
Then I got a note from a guy who said he never logged in but visited the site everyday. He was surprised to find out he was no longer a member. So I quit doing the deleting thing and dumped that IT guy. I felt bad about following his advice and wonder what the real count would be today.
And like snapper said, we have a great membership who so willing shares their advice, experience and friendship. Actual headcount is not that big a deal.
