I have written on numerous occasions about my advocacy of iCalendar as the means by which, I believe, time-related information should be disseminated. (Unfortunately I'm not too good at articulating why but thankfully I don't need to be because Dilbert creator Scott Adams has done a fine job of that in his blog post Calendar as filter). To that end I tried to start an initiative earlier this year where folks hosting SQL Server webinars around the world could make information about their webinars available in an iCalendar feed and I would then use an aggregation service (called ElmCity) to produce a single feed containing all that information so that the likes of you and I could subscribe to it and see those webinars turn up in our smartphone/Outlook calendars. Unfortunately I couldn't round up enough willing volunteers (thank you to the one person that did contribute) so it didn't get very far.
I was, therefore, pleased to see that John Sansom (blog | twitter) has begun a similar initiative for aggregating information about SQL Server user group events in the UK; the difference being that John is maintaining the calendar himself and inviting others to contribute rather than using an aggregation service like I was trying to do. John has made the calendar available for subscription at https://www.google.com/calendar/ical/gnbu8hpgv4f1gpnueo8lif06mo%40group.calendar.google.com/public/basic.ics which you can subscribe to using Outlook, Hotmail Calendar, Google Calendar etc... If you use one of those online services (like Hotmail Calendar or Google Calendar) and you have that account synced to your smartphone then it should automatically turn up there too.
If you want to learn more go and check out John's blog post on the subject at SQL Server Events.
Great job on setting this up John!
