I am running project X or X & Y but I only want to run Project Y

UD may have a number of different projects currently active and there may be times when you are running a project you don't want to and you want to make sure you no longer participate in it. This is done via the Device profile and is very easy to do as UD have always given the member to option to opt-in or opt-out of any of the projects they run. The only limitation is you must be running at least one Primary project. For each PC, check what device profile it is using and edit it. Opt-in or out of the projects listed and save it.

You now how 2 choices: 1) Let the current Work Unit (WU) complete or 2) dump it.
