(Thought about posting this in Help & Support but decided this is not a matter in Sonarr’s control)
Sonarr has the tvdb: prefix while adding shows. Helpful, useful, precise.
Better still, a quick Google for the show name would likely show the url, which was something like http://tvdb.com/show/id=123456 (I can’t remember what it was exactly), and the ID was right there for copy & pasting. Everyone was happy (I presume, I never asked).
Now TVDB have changed their naming to the much more human readable but ID-lacking format: https://www.thetvdb.com/series/show-name
With this in mind, what’s a practical, fast/low effort way to get a TVDB ID these days?
