Hi,
would it be possible to have a capability to subscribe to receive notifications about comments that are posted under activities?? In a similar way to which you can choose to receive updates to forum threads or comments in Groups.
At the moment I think the organiser is notified about comments but not other participants. It could be useful for things like organising transport for hikes.
Of course, this would be an opt-in, Off by default setting!!
Cheers
Kathy
