Keeping SC text in the pull request description

If we stick to pull requests as the place for discussion, then I recommend:

Keep the up to date SC text & new glossary terms in the description of the pull request.

That way it is at the top, and (assuming the SC manager does the pull request) it can be kept up to date.

I had issues on a Resize text where it went through a lot of change, and people were referring to the old version in the issue, which I couldn't update. Frustrating for everyone, so it seems best to keep it up to date at the top of the place it is being discussed.

Cheers,
