Scheduling meetings can be a time consuming and frustrating experience. Thankfully there are a number of freely available web tools which can help avoid the all too familiar email ping-pong experience. Three options are:
Doodle is a doddle. You just enter a title for your meeting, your name, and your availability. Doodle will then provide a web link to email to colleagues.
Congregar is similar to Doodle but is perhaps a little less intuitive. Meetings can also be scheduled for a particular day but not for specific time slots on that day.
Meet-O-Matic has an older style interface. Meetings can be scheduled for a particular day, and for the morning or afternoon, but finer control of times isn’t available without registration and subscription.
