 ## Extension Of Bounty Issue's Timeline
 
-In case a response critical for the technical resolution of the Bounty Issue is delayed in [GitHub](https://github.com) and/or [Slack](https://asyncapi.slack.com) for a period of more than three consecutive working days, all remaining target dates of the Bounty Issue's Timeline are increased by one calendar week per each of the three consecutive working days the critically important response was delayed, plus one calendar week in case of two and more periods of the three consecutive working days. 'Plus one calendar week' period is required because after the critically important response that was delayed for a significant amount of time has been given, the Bounty Program Participant would have to spend time getting back to the insides of the issue and nearly unfamiliar at that time their own code. 'Working days' are weekdays, from Monday through Friday. Friday and Monday may be considered consecutive in the sequences 'Thursday-Friday-Monday' and 'Friday-Monday-Tuesday.'
