Review on BusyCal by Troy Boettcher

I like that it syncs with Google Calendar, so when you add an event to your google account or change its details in there (eg time), they sync over here too! It's not always perfect though - sometimes events won't show up until after i've changed their start/end times etc; also if someone else adds something at the same time as me then my own new stuff gets moved down below theirs. If anyone uses this software, make sure you have backups of all data stored within because we had some issues where our entire busycal database was lost one day due to server problems which meant everyone couldn't access anything from that point onwards. We were able to get back into everything but it took ages and hours worth of work by multiple people doing research through old files before we could finally restore things how we wanted them again.
