Pat, I've said before and I'll say it again. You did a good thing giving the rest of us a nudge about making the new people as well as the more quite ones welcome here. Personally, I needed that nudge!
To tell you the truth, I don't understand why anyone would take offense to that.
Please stop beating yourself up! You know as well as I that you can't please all of the people all of the time. It's time to just relax and know that you did a good thing. You're not responsible for other's feelings or actions.
