I'm a creature of habit... Once I get accustomed to the look and function should not be a problem as long as it works properly. I applaud Anthony for doing the tests before the switch. I worked for a company that the IT dept sometimes would make changes, not tell anyone and shut the whole place down.
It's like getting a new car and trying to figure where the wiper and heater switch is the first few times. Your brain keeps going to the old spot for a while, in a week it's fine. New site works for me
