For best participation here, it is recommended that you register and get a login name. The "GUEST" will disappear from your posts, and you will be able to access several useful features of the site that are not available to unregistered visitors.
At the top of each page here, there should be a box that says "Quick Links." Click the little arrow/triangle and choose Log In, and then click the "GO" button and you'll get instructions on how to register and become a real "member." Free and no hassles.
Regarding Wireless:
Some may have not noticed that the German Courts have ruled within the past couple of weeks that if you operate an unsecured wireless network that is used - with or without your permission - to download and/or distribute copyright material (or SPAM) - YOU are liable for usage fees and fines, even if you are not aware that someone is using your network. Since anyone who finds your network and "piggybacks" on it can access any place in the world, regardless of where you live you could be subject to hefty expenses if you don't set up adequate passwords (at a minimum) to reasonably protect your wireless setup.
