I am a Mac user at home, and i won't say i am GREAT at it, but i am getting there by trial and error. My Mac has so many features i still have no idea how to use a year after i got it. But i mostly just take the templates that people have created here and try to re-create them the best i can using Mac based programs. MOSTLY it works pretty well. (Of course, i download them at work on my PC and then try to make them work at home and compare the two!)
I can tell you this - if you are thinking of doing ANYTHING from VistaPrint, their editing program (for customizing) is not compatible with Safari. Hmmmph... in this day and age!
Hopefully some techy-wizard type can come along and help us both with tons of useful information... right? Anyone?? Bueller??
