Hi Robb, this is a great idea!
While we haven't done a big campaign like this I would highly encourage it as the system will be successful by as much of demystifying / barrier-reducing you can do. Having users understand the flow of requests so it isn't scary or a "black box" will help with maintenance going forward as well tweaks needed. To that end I have a presentation on our broad Lucity integration I share with new users, also a custom user guide on our mobile workflow, and a template welcome email that includes links to the Lucity youtube channel for relevant user videos i've uploaded those resources here https://drive.google.com/drive/folders/1ZoeD0F7ffBH9XtZVV-jiunizFmaHIGc4?usp=sharing I used icons from thenounproject.com
We also do "refresher" presentations from time to time to remind users of certain functionality, new tools in new versions, and changes to workflows.
