That forum seems to be tucked away "off the beaten track" which may explain its less-than-enthusiastic participation ~ if you build it they will come; if they can't find it nobody will show up. Given the distinct affinity programs of the cruise lines & the respective program cross-overs with the airlines, etc. it makes sense, to me at least, to have forums for the different cruise lines listed amongst the other airline, car, hotel, & credit card program forums.
