I have the Add event working, and the Add location, and they can edit locations from the list, but there does not seem to be a way for a front-end user to edit an existing event. Am I missing something? Or is this not possible currently?

Its in the host menu.... Edit the "theme" that the even is using, and add the hostmenu placeholder somewhere.

Aha! Thanks! However, I added it, and nothing shows. (I double-checked that the group my user belongs to is in the editor group on rsevents - not sure what else to look at)

After looking, it says I need to install the hostmenu module, but I can't find that anywhere. It does not appear in the downloads section for me.

Ok. The module is there (must have been added when the component installed?). However, I still don't see anything, anywhere. The module says the position is none - should that still work, since I am putting it in the theme?

Hmmm. Guess I will open a ticket. Feeling kind of dumb right now, but I'll get over it! It is probably some stupid little setting that I am not seeing.

it's just a bot.. If you find a solution for your problem, can you post it here so others can benefit?
