IT is a free program, and people answer question as volunteers, it is counter productive to get annoyed or even a little miffed at any answers you recieve. I'm not a programmer or even an IT person, but I find the program very easy to use. Email options are not universal, and always depends on the attachment having a "standard" file extention like JPG or Gif usually to be read in others computers, but that isn't much of an option for Open source freeware, since you have to remember about licensing and copyright issues.
You can save your project as an obj file and email that you know....
