Tomorrow the university reopens but it turns out the answer was there in front of my face since December-- I have two university-related email accounts and in one, there was a message about a Blackboard-related training session. Hit the webpage url listed and BAM-- the Spring schedule for Blackboard training. Signed up for the introductory and will take a variety of other courses into the coming months.
Let my supervisor know that I'm interested in online teaching and ask about a fall class.
Get certified and then teach from anywhere, just like Steve had told me.
Coincidence? I think not.
Serendipity, I tell you.
