some good replies, I had to laugh at the brick with a note, classic! I reckon you are old enough to remember knock on ginger lol
working in pj's or boxers, that is the way to do it
It seems like most guys are keen to keep communication at the top level and respond quickly, skype IM is defo a must.
I think the worst I have had is trying to communicate with a guy who would ignore emails for days and then just not bother to reply, and even pick up the phone and not speak.... this is a guy who promised to do some work but for what ever reason could not be bothered to communicate ... I think he had a screw loose though or was into playing games.
Keep up the good work to all of you who communicate well with your potential / current customers, it will pay off in the end and you will get the word spread about for good reasons.
