Process/checklist for when an employee leaves PhET

[ariel-phet]

@amanda-phet suggested awhile back we need a process and checklist to make sure various items get addressed when an employee leaves PhET. This would be good to discuss, potentially even at Status meeting. I have made a draft checklist here:

Assigning @amanda-phet @oliver-phet for input.

Here's the CU exit checklist I use, if it helps: https://docs.google.com/document/d/0B3aB5oT9c4e0R2VrTXVWd0pleFU/edit

I think explicit notes to delete from the team page, slack, google group, and google drive are needed, and who is the point person for doing so. I frequently find people no longer affiliated with PhET are still visible in these places. There's an especially important but annoying task of finding all files in google drive that may have been individually shared with them (or created by them) that simply removing from the google group doesn't resolve. I have sometimes taken it upon myself to take care of the task (I've done it in all of the mentioned spaces) but it would be much better if we consistently removed a person from all spaces at once.
