When I add meetings from a central office I e-mail the office letting them know what I'm doing and ask for feedback. So far the only office to respond has been LA. They invited me down to their monthly business meeting to talk with their db and web guys. I've never been to the CO and it was nice to visit. I learned that there are different standards for what goes on the web vs the printed directory. The printed directory has more meetings than the web but they said they are closing this gap. Anyway my main point was to make them aware of my use of their meeting information and to make sure they were okay with it. They were, stating the meeting information was in the public domain.
If there are other central offices that have feedback, questions or want to be included on this site please leave a note here with some your contact information and I'll contact you.
