Fairly obvious practical detail --<p>I'm at someplace new, where I don't have internet. I see if there are any open networks, no dice, but I see an encrypted network as www.wifis.org/poop. I think "oh, great, maybe my neighbor is friendly and I'll just go ahead and emai-- wait, I don't have internet, so I can't even visit the link."<p>Later I'm at a coffee shop seeing if FiOS is available in my area or double checking whether or not I live in Kansas City, and I think "oh, right that URL", but by then it's already disappeared from my SSID list.<p>Who's gonna have the forethought to write the URL down?<p>Explicit instructions in the SSID itself might encourage people to jot something down when they do finally get internet access. SSIDs are limited to 32 chars. The best I could come up with was:<p><pre><code> ask me for access:hi@domain.com
</code></pre>
Of course, even better would be to do something clever like -- make an SSID called "Friends in Building Wifi", that's open access. Upon connecting, you get pushed a page that says "Want to share my bill? Send me a message with this form". The message then gets passed on to you, and then you can go walk downstairs and chit chat, or whatever. This way your neighbor can message you without requiring internet to do so, as wifis.org does. (And then, naturally, put your actual internet on a different WPA2-protected SSID.)
