Well I did a hotspot today at Brighton...
#kevinlyclass - jwfacts.com
I did not let anyone join it to prevent any risk of being hacked or me accidentally outing myself but I did get a message from one person on this board saying they saw it. Hopefully others did too.
The only thing is that the HS turns off after a while due to lack of connections and I've not found a way of keeping it on. Another thing I would like to do is change the SSID every hour or so to a new message but it's a bit difficult to do that safely at my seat and I don't want to be up and down all the time. Perhaps there is an app for that :-)
When I last did it at Haysbridge the attendents saw it and there was loads of activity as they thought there was about to be an apostattack any second :-) Didn't notice the same activity at the Amex though...
