[Discuss] What's the best secure groupware package?

[E. William Horne]

Thanks for reading this.

I'm looking for an open-source encrypted groupware program that is both 
secure and easy-to-use.

I've looked at W.A.S.T.E., but I don't think it's being maintained, and 
I'm looking for packages that are currently being supported.

It would be nice to have something that has versions for Mac, Windows, 
and Linux, but security is the most important criteria.

I appreciate your time.
