NNTP seems to be a bit low-tech these days with dwindling support by new clients. But I might be wrong on that, will have a second look. You totally got my point: E-Mail is distracting and people feel stressed by the amount of mail they receive, while on the other hand they feel not informed enough about various topics. And you also give sensitive data into external hands and hope it will not get leaked or breached. I think self-hosted "board software" (in whatever shape it comes) might reduce distraction, you can read and write when you want and people from other departments can keep up with current developments and also chime in if they have something to contribute. And with something like phpBB you also have full and easy control of the data. I think that's an important point, especially for companies. Might be worth the discussion and a try with a small team.
