It takes a day or two for them to disappear for two reasons: people may want to see what you just did (if they see you, then go to your web site to find out more about you); and, more importantly, LaffQ doesn't keep track of time zones, so it doesn't actually know the moment a show starts, since it could be in the Christmas Islands or Hawaii, which are over 24 hours apart. So there are a small number of shows that are in "Past Gigs" and "Upcoming Gigs".
In theory, LaffQ could look at the address and try to deduce the time zone, but that would require a big database look-up, so I'm punting for now and keeping shows around up to 24 hours longer than one might expect.
Yes. The magic URL is <http://laffq.com/YOURUSERNAME/ical/>. Point iCal or Google Calendar at that URL and it will know what to do. Somehow. But change YOURUSERNAME to your user name. Not literally, but whatever it is you selected your user name to be.
Then messages from us will go into your Facebook feed. Or Twitter if you prefer.
Facebook works well. Message us here. Write on our wall or something. Whatever. We'll see it.
Your data is stored on a large commercial web hosting service where it is backed up hourly and copied off site once a day. If you're really worried, you can download http://laffq.com/YOURUSERNAME/json/ once in a while and you'll have all your shows in slightly-difficult-to-parse-by-humans-but-easy-to-parse-for-computers JSON form.
