Thanks for reply, Peter.
That's it, it's free for non-commercial usage.
The MS viewer is what we wanted. Just to be abe to easily view Office files, PDFs, etc. directly in browser. Afterlogic also has its commercial version (Aurora, I think), which has colaboration, etc. Anyway, Im a fan of Group-Office too
Just a small suggestion, perhaps could include the free MS viewer service that could work out of the box. Some customers miss that, for us and for many users it would be enough.
