heh, GitLab (.com, not the Wikimedia one) notified me that a personal access token is expiring in <7 days
according to the list of tokens, I created it on 16 November 2017, and it was “Last Used: Never” (which I suspect really means “before they started tracking usage information”)
I haven’t the faintest idea what I created the token for… guess I’ll just let it expire then
