Tungle is a great service for calendaring, no matter what platform u use (google calendar, exchange, ical, etc). it lets the person that wants to schedule a meeting with u view your available times, they propose times, and u pick the time u want. this definitely helps when ur busy. oh and its free, and only requires u to have email. best of all, once u select the time, ur calendar automatically gets updated.
this will definitely work if i become an academic at a university. I already embed the link on my website. now should i embed the link in my email signature?
