Here's what I'll propose:
- Retag all questions tagged shield that refer to EMC shielding to shielding
- Get rid of any non Arduino shield questions tagged shield
- Merge shield into arduino-shield and
make shield a synonym mapping to arduino-shield.
- Change the arduino-shield [wiki]1 to include a reference to shielding
I'm suggesting that we make shield map to the Arduino usage to reduce workload. If you look at the majority of the questions in shield, they are Arduino. I suspect EMC questioners would be more likely to distinguish between the two usages, and would result in the fewest false taggings.
(upvote/downvote as you see fit, and I'll revisit this in a bit.)
I ended up retagging 3 out of the 34 tagged questions that were EMC related, and I merged the remainder into arduino-shield. The shield tag should delete itself automatically in a day or so as long as nobody adds a new question. We'll try it this way and see if it sticks. Below is an image of the tag dialogue after getting rid of the shield tag:
