After rumours and
rumours, now Google
Calendar is officially out.
The features added are really interesting: you can share calendars, invite
guests to your events with just a click, activate reminders and Gmail
integration (Gmail now recognizes when messages mention events, so when you get
emailed about an event, you can add it to Google Calendar with just a couple
clicks).
You can also import Calendars from Outlook (wonderful!), so you can
always have your appointments with you wherever you are. Now I'm waiting a quick
link inside the Gmail main page to open the Calendar.
Thanks Google
