Perhaps I am missing something, but sometimes, just sometimes, it would be extremely helpful for me, as the band manager to manually accept on behalf of somebody. Perhaps they've called me on the phone to ask me to accept for them, etc. The only way I see to do this is to log-in under their password and click 'Accept'.
Am I missing something?
There's no way currently, but this is on my wish list and I'll let you know if I can work it in.
With today's release, you will now see a Move a User option on the event edit page, which you can use to manually move users between the Accepted, Declined and No Response states:

You do an awesome job, Arlo. This is very helpful. I'll give it a try.
