It would be nice if we could set some kind of "out-of-office" on a user.
This way, people creating issues for that person, or commenting on issues on which that personwas working on, could get an e-mail notification that person is out of office for a few days/weeks.

This plugin can be used Out Of Office Assistant, Please contact the plugin vendor in order to make sure about functionality as Atlassian does not support third party plugins.
