:(top left corner will see a button that says...compose...hit it and a page will open type what ever you want to say in the body of the page at the top type in the e-mail address that you are sending too. hit the send button..you have just e-mailed!!
Do you mean e-mail people within a YAP open application? If that is the case then there is not currently functionality to automatically e-mail an individual from an application. You can use the yml:message or yml:share tags to send messages, but these are user initiated events.
