My Wifi access point used to be open to anyone, with the name "noP2PwebOKthanks". What this meant was that people were free to surf the web, but politely requested not to download movies, films, or anything else that would get me in trouble.
Of course, this didn't work, and after too many times of having slow access to my own connection, and exceeding my bandwidth quota, I added a password. The wifi network is now called "bit.ly/1wflj1", which is a link to this blog post.
If you used to use my network and enjoyed free Internet access for occasional use, then you can still use my wifi - get in touch with me and I'll see what I can do.
