Hello - I am the original poster and wanted to follow up. Thanks for those two pieces of info, kkirksey - good stuff!
The meetings turned out well and I would encourage any organization to take some time to have this sort of conversation. Considering how much time goes into email, it is a great thing to come to agreement on what your "rules of engagement" as an organization are....
I ended up with two discussions about email - one at a yearly retreat with my two bosses and one of my co-workers and another at our staff meeting. The discussion at the retreat was great - just buiilding awareness about what email costs us in terms of time, torture, getting pet peeves out on the table, figuring out how we can be more productive. It was one of the healthiest conversations we've had in awhile - we learned a lot. We ended up spending much more time on this than we thought we would and my boss commented that he was surprised that a talk about something as mundane as email could be so "intense".
We had a similar discussion in our staff meeting, but had much, much less time, and I felt like I was presenting more than generating a discussion (yuk), but it was still helpful to hear how we our gets driven crazy with email, how we can be more effective, and come up with some basic rules of engagement.
Thanks for your help.
