@selfsame I wish certain programs would offer to let you normalize the forms.
Not sure about most countries, but IIRC "0" and "1" are both used for moving around exchanges (011 is the US exchange), so I don't think area codes or exchanges can start with either.
That would make the regular expression nastier though. :)
@selfsame I do like the trolly lever though. :) Half my entries are one or the other because I can't easily normalize them. It just grates when I see it. :D
