When you propose a meeting, for instance, automatically e-mails the invitees up to five possible meeting times of your choosing. The invitees vote for the times that work best for them.

TimeBridge also lets you set up and conduct free conference calls, though I haven't tested this feature.

FreeConference: Free Confabs, but Toll Calls

I've used for years to set up and conduct telephone conference calls. It's easy to use, and it gives you lots of options.

With a free Web-Scheduled Standard conference, attendees dial a toll number to participate. However, you can give attendees a toll-free number with the Web-Scheduled Premium 800 service. The cost is 10 cents per minute, per participant. The Premium service also lets you share your Windows or Mac desktop with others or record your conference calls at no extra charge. You can add either desktop sharing or call recording to the free Web-Scheduled Standard plan for US$6.50 per call or $9 per month, each.
