I enjoy reading these boards so much that I find myself wanting more. Please post more websites if you know of any. Or just ask twice as many questions and get twice as many answers so I have something to do at work.
the Latitudes and Attitudes web site http://www.latsandatts.net/
bulletin board is very active, but you have to wade through alot to talk about sailing. There was a post there recently, on page 2 in Gregs Pub that asked for others to name favorite message boards. have fun.
Another decent site, especially for the Caribbean is http://www.traveltalkonline.com/forums/ubbthreads.php
or if you like irreverence
Or as newby says check out the lats & atts site.
