It is just a count of posts. Not a measure of usefullness.
I can assure you I have gotten a lot more out of this site than I could ever put back in.
The computer is in the office as is the kettle so when I stop for a cuppa, look up a part or write an invoice I take a quick peek.
Being in a different time zone it just happens that I am on line when you lot are not so I get to see most posts before other techs in the States.
