Henry, I find it very odd, too . For some strange reason "Meet Onboard" on this site hasn't (at least as long as I've been here) taken off like some other's do .
The only "Meet Onboard's" on which I've seen a lot of postings are the CM's sponsored cruises.
I wish someone could explain it to me, too !
Fern.. there is an answer..but I'm sure NOBODY on this board will agree...On our NCL Gem cruise there was such an enormous Meet and Greet from another board (well over 100 people) that NCL went out of their way to have a private presention of staff at the M&G (by the way I kept mentioning I was from Cruise Mates..lol), then sponsored a special Italian dinner (with the dining room closed to the rest of the cruisers that evening) and a private special dinner in a closed off area of another dining room. It is obvious that the cruise line went out of their way to treat these cruisers from the other board like precious jewels. At one point i heard that there were over 400 postings on that site. Many of the cruisers I met were devoted NCL fans and I must say a very welcoming and friendly group. So, folks.. the answer is honestly they are somewhere else. I've posted my next trip on this site and haven't heard from anybody.. although people found me on a third site..
