Suggestions for SF webinar?

I will be hosting a SF webinar next Wed, Feb 28th, similar to last year's webinar (https://www.census.gov/programs-surveys/acs/guidance/training-presentations/acs-summary-file-2017.html)

Any suggestions on content to cover for newish SF users? 

Any examples of how you use the SF that I can include?

Thanks for your feedback,

Gretchen
