I replied all right. I told my supervisor his email was a mistake because I’d never heard of any such system. He wrote back about a training a few weeks prior, but I insisted that he’d forgotten to schedule me. He politely wrote back again with more details, so just to prove him wrong, I checked my Favorites.
I found the link to the system bookmarked in a relevant folder. And yet I still had no clue what he was talking about.
