Kim,
Yes, the two CC-get-together that I'm aware of were one in CO before Alayna's wedding and then at Alayna's wedding. There was also one in Canada for Canadian CCers.
Last year, I went to TX to hang-out with Reinitin, a CCer from chat. The original plan was to meet some CCers in TX who have become my friends, but our schedules were off. Bummer!
It's also true that one get-together got cancelled at the last minute because some of the peeps were like, MIA afterwards. Bummer.
