Hard to find a time when everyone can meet?
Schedule Once is an add-on for Firefox and Internet Explorer. It helps you schedule meet ups. And it can connect directly to your Google Calendar. There is also a Web interface for those who don't use Google Calendar.
You select a period of time in which you’d accept a meeting. Then send out a ScheduleOne invite. Others select their own availability. The program automatically finds common times without scheduled tasks.
