Doodle makes it really easy to schedule meetings by creating simple polls to find out when your attendees are available. Doodle is particularly helpful when the attendees are outside the Lab (and don't use Google Calendar).
You may already be familiar with the free version of the scheduling service. The good news is that you can now access an ads-free version with LBL branding completely free of charge.
