A-Z challenge? ...... explain

I'm completely out of practice with tags, most people do an A-Z challenge with animal breed names or types, I made it about character's names.

So i have a list of a bunch of people's characters i'm going to do tags of, for free, in hopes to better myself at tags, or get myself more comfortable with them. And to get my name out there in the community.

For me this is a challenge simply because I can't find time, with school its hard.

may have to try something like this myself
