It wasn't that no one thought about that. It was just a small get together (nuthin' fancy) to meet some of the new staff. They've been going like crazy to put together roster, staff, etc so haven't had a chance to really get out and meet folks. I know that Chaia wants to have other bigger events.
There are a few thousand Braves Club members, so having something for that group would be a much, much bigger undertaking. Obviously you are in the top percentile of those members, so I am sure something will happen sometime in the near future.
There are also a bunch of new coaches - softball, women's golf, tennis, women's basketball - so they're trying to get all of those folks up to speed on their program's alums, donors, etc while they try to put together rosters for next season quickly. With the new changes to how they are handling annual giving, there will also be a lot of conversations to be had about Braves Club, sport specific, and all types of donations and benefits for those donations.
