Heading Navigation in GitHub Issues

I just tried an experiment. I added an h2 tag to the comments list on Issue
75. I made it h2, and it should have been h4 but the concept worked.
The comments follow their chronological order. So I propose Inserting a
comment with ### Month the first day of each month. So on May first the
manager of an SC enters the Month. Next, on AG day Tuesday, enter the date
as an h4, #### Date. Then we can use heading navigation to step through
the comments. If there is a change of topic just enter an h4 with the
Topic, ie #### Use of Mechanism.
It is informal and relies on WG maintenance, but it would help a lot.
