Help CenterRunners on your favourite list already have priorities to receive notifications first. However, the pool of favourite Runners can become too big, and there is a smaller group within it that you wish to give even higher priority. This article explains how this can be done.
When you create a timeframe, on the "Hiring Runners" step, you can see an "Invite Runners" button per the image below.
This will bring the Runners from your favourite list. You can choose the ones you would like to invite. This will give the invited Runners 30 mins to react to the notifications. If they miss it, the rest of the Runners will be notified.
