I have a field that sometimes has a mentor's name in it, and other times (usually) is empty.

I am showing that field in a timeline - which is fine when there's a name, but otherwise it shows up as "(empty)" which is annoying

I want to create a formula field that shows the value when there is a value (a name), but shows something innocuous - like an asterisk - when it's empty.

I feel like this is an IF statement - but the value of the field is different all the time - Joe Schmoe, Jane Doe, etc.
