The concern is not about boats, or the people who own them. It's a matter of personal security.
I don't post under my real name--Max knows who I am, so if there's a problem with something I post, he can let me know. A lot of other mudcats know my real name, and know me personally--I count them all as good friends. And Reynaud and I looking forward to meeting a mess of new mudcats at Middlewich.
However, at the risk of seeming to be paranoid, and/or of boring those who either share these thoughts or who have read them here before, here is the issue. Many many people read the postings here. Some register, some post as "guest" and many more people read what is here than register, post or reply. A few of those people may not have the best of intentions toward those who do post, and might welcome the opportunity to know where and when to find them. My concern is akin to the general advisory not to post your email address, telephone number, or directions to your house on the forum.
I hope that clarifies the issue without offending anyone...
