I am VERY new to all this -- but one of the first thing I notice (after connecting at a time when there were few controllers on "duty")is that it appears that the info given by Wazzup as to how many controllers are operating and where they are seems to be at odds with the online info given out at the VATSIM website.Any comments please? - and what is the best way to determine where controllers are operating.?

There is a good 5 minute DELAY or so between what you experience on vatsim/squawkbox and Wazzup/ServInfo. Vatsim.net as well as the ATC Directory in Squawkbox are the only ways to know which controllers are on-board. And don't depend on the gauge provided by ServInfo either, it too is delayed.Randy Jura, KPDX
