If players don't /accept or /deny a request, they will continue to be asked until they type one. It would be nice if this was just a one time message.

There is a setting requests.max-asks-per-request in the new builds that you can use to limit that.

Thanks. Sorry about that. Do I just set max-asks-per-request: to 1?

Correct, though I would put something like 3 in case they don't see it the first time.
