How would you keep Joe informed?
I agree with Roger that it's not a stand-alone action, but an outcome: "Set up project xyz status reporting agreement with Joe". It's a process project.
I wouldn't necessarily track that as a project, because most likely I could set up the agreement by having a single conversation with Joe about how he'd like to be kept in the loop (weekly status meetings, weekly status e-mails, etc). Then I'd set up whatever recurring reminders I'd need on my calendar to make sure I fulfill the agreement with Joe (Every Friday: E-mail project xyz status to Joe, for example.)
