I've occasionally thought there should be a tag for "curvy calves," and I'm wondering if this is something it would be acceptable for me to create. I've never created a tag before, and I don't want to do it if it's not something other people would appreciate and use themselves. I'm also wondering if it would be better as a pool (I've also never created a pool), though I do think it's more objectively descriptive than pools are meant to be. Um... I'm assuming the way to create a tag is simply to add it to an image's list of tags. If I did that, I'd probably feel a compulsion to start looking through practically every image on the site for things to add the tag to. How many years would that take, I wonder? Also, when one creates a new tag, is it a good idea to also create a new wiki entry for it, even if I don't have much to say about it? And do wiki entries automatically get linked to and from the tags they're about?
I apologize if most of these questions are answered in FAQs. I've looked through some such things, but didn't come across any answers, possibly because I'm unobservant.
