What can't we use in our public facing chapter art and graphics?

No combadge type deltas that were/ are used on specific shows.  A generic delta shape is compliant.

Obvious starships, i.e. Enterprise D flying at us, a generic Galaxy class (with your chapters name and reg) should be fine.

You should also run the creation through the Compliance Officer, David Yee (compliance@sfi.org) if you are unsure, who will then make sure they're compliant and don't breach IP.

We also have a handy guide for chapters to refer to as well.
