I noticed that we have 2 tags for amplifier. I propose we rename the [amplifiers] tag to [amplifier] and merge in the [amp] tag.
I changed everything tagged [amp] to [amplifiers]. Still need to rename [amplifiers] to [amplifier]
The only way I can find to rename a tag is to create one with the desired name and retag all questions removing the old tag and adding the new. If someone else has the time please feel free to retag them (currently 25 questions). If not, I'll get to it in a couple of weeks when I get back from vacation.
