Then I get http://cruising.sailboatowners.com/, which doesn't display the actual BBS. That is using Mozilla Firefox 3.xx on Win XP

Using EI, I get this: "Internet Explorer cannot display the webpage"

Now bear in mind that I am trying this from different web connections (both work and home, and even VPN) and different computers... and (if it matters) I am on the west coast.

While CSBB does show up as the first link Google provides, that link does NOT actually give you CSBB... it gives a blank page. It appears to be CSBB, until you go to the URL. In reality you need this URL to give you CSBB: http://cruising.sailboatowners.com/csbb/index.cgi
