Right, I have done some digging with the help of El Presidente on whether this is feasible. His conclusions are much along the same lines as mine. He believes that publishing this sort of data, no matter how innocuous it seems would probably fall foul of the data protection act. There would also be the fact that a list of every boat and its location could be a potential thieves shopping list.
If everyone wants to publist their details via the forum then that it is their responsibility and their actions. The class association cannot be found to be in the position of publishing information contrary to rules of the data protection act, so our apologies for that.
