should this file be moved to event/new/page.tsx, to make room for a future event/page.tsx that lists all the events?

and should /event be renamed to /events for consistency with /users? cursory google search says plural is preferred

sorry just noticed this now

[jakehobbs]

i think i was thinking that /event/list would be for the event list. no strong feelings, but will revisit later.

[alexsapps]

ok sounds good to revisit later. just for the record my reasoning was it's easier to let users change the url themselves, at least to go up, e.g. if they see /events/218 or /events/add they can remove /218 or /add to go up a level in the navigation. i think of the list page as the highest level in that navigation hierarchy because it will usually provide all the other links.

i just tried this out in prod, and i noticed some changes don't seem to save.

to reproduce:

1. open an existing event
2. remove someone, hit save
3. add same person back, hit save
   result: their name disappears again / they do not get added back

similarly:

1. open an existing event
2. add someone, hit save
3. remove the person you just added, hit save
   result: they do not get removed / their name reappears
