My question was closed. While closed, it accumulated comments from people who could potentially answer, not just comment. After reopening, I wrote a very brief comment to each person, inviting them to answer if they are still interested. I pinged (at-mentioned) each person, with 1 comment per person to ensure that each one is pinged exactly once.
Should I use the per-site Chat instead?
What is the accepted method in such cases?
Add the ability to automatically follow a question on which I've added an answer or comment - This automatic method would have been a great replacement for the manual, time-consuming method discussed in my post, above.
