Why aren't we doing this when we finished 4.0, i.e. merged all the voted in
pull requests into the standard?

> * Participation to the forum has a barrier to entry (i.e. me)
> * Our current automated testing system is broken and will not be fixed
> * We rely on special dispensation from GitHub for free, private repositories

> The plan is for me to flip this switch DURING THE FEBRUARY MEETING! This should
> not disrupt any readings for the meeting itself as none of the pull requests
> will actually be deleted, but they will all become stale and we’ll need to
> re-open new ones. The main benefit of doing this during the meeting is that
> if/when anyone has trouble, I’ll be there in person to provide live help to
> anyone else that’s there (sorry, Marc-Andre, you’ll need to follow my slides
> remotely \uD83D\uDE00).
> 
> Please email me if you have questions or concerns. If there’s enough demand, I’d
> even be willing to do a short Virtual Meeting on this on Wednesday.
