If you want to exchange with your friend or workmate,
some Calendar appointment, Task, or Contact,
easily, efficiently, and wireless...

this program is a very perfect program for you.
because you don't need learn anything more.

You just see a new menu "Send by WeAreTogether",
in your default Windows Mobile Calendar, Tasks, or Contacts interface.
You only have to select appropriate item, and give the number of friend's phone,
where you want to share (send) the selected item.
Recipient will get a message to accept,
and your item will add automatically to his/her Calendar, Tasks, or Contacts.
