A great idea from Ben Malone http://www.bimdiary.com/
BIM Diary – Calendar and information for all upcoming BIM related events; online and offline. If you want to add an event to the calendar, post it on Twitter with the hash tag #BIMDiary and I will get it added to the calendar as soon as possible. Click on each of the calendar entries for more details and registration information. All times are listed in UK time (GMT). Online events are displayed in red.
