I think it's cool you will be able to send your T cards. I have my former T's home address and I plan on sending her a Christmas card. We don't live in the same city and it's quite a drive for me so there's a pretty low chance that I would ever even be on her street. I think she felt comfortable giving it to me otherwise she wouldn't have. I've had it for years though. One time to send her a card before she went abroad because for whatever reason she couldn't make it into the office before her trip. But I'm glad I have her address now.
