* The last place I worked had posted office hours for all the teams and that worked _really well_, especially if you didn't know who, exactly was responsible for X, or if you just had a hodgepodge of semi-random questions about some overlapping functionality. In hindsight, it might have been even better if we recorded them and posted them with a short outline of discussion topics.
* Don't underestimate the value of having a designated meeting secretary, who's responsible for taking notes and posting them to a central repo/confluence/wiki/whatever. If you're going to have group meetings, maximize the value. This can and should be a rotating responsibility.
