Collaborating with Mellel

I'm using Mellel and wish to collaborate with my colleagues. They have a Mac, but they don't have Mellel: how can I collaborate with them? 

The easiest way to collaborate with colleagues that have a Mac is to simply tell them to download Mellel. Any user of Mellel, registered or not, can open Mellel files, change them, track changes, add comments, save the files, and of course send them back to you. Best of all, they can do this free of charge — all they need to do is download the trial version of Mellel. 

In fact, collaborating with your colleagues in this manner will assure you maximum integrity (styles, fonts, layout, etc.) with minimised hassle, because your Mellel files can be sent as they are, without any exporting, used as they are, then returned to you.
