Note: This has already been completed. I'll leave the question for reference :)
Before we do this, of course, we should set up tag synonyms (background here). I've just gone in and proposed synonyms for most of these tags.
There are a few things left for us to do:
Go and approve the synonyms, if you agree.
Delete a bad synonym proposal I made a long time ago. It is no longer the correct way to do things, and it is keeping us from proposing the correct synonyms. I assume that a mod can do this? The tags in questions are stm32f10x as a synonym for stm32f10.
After some time has gone by, a mod can merge the tags if it seems appropriate.
Does this sound like the thing to do?
