For cooperation with other people, its often handy to share screen shots. One screenshot at right time saves a lot of words.
Because screenshots can contain private information, its handy to use cut before sharing. There are several ways how to do it - for example using editor like Paint.Net. It works but its slow you have to paste screenshot into editor, cut it, save screenshot and upload it to some screen shot sharing web.
There is a better way. Using SnipBoard.io you can paste screenshot directly from clipboard to web page, cut screen shot, save and share. Its amazing time saver. Bookmark that!
