Create a nice author listing page

I want to create a nice author listing page. Here is, in my opinion, the easiest way to do it, although correct me if there’s an easier way. I already have styled my individual author pages to a point where I like the way they look. So here’s what I’d like to do to make the full listing.

Start with a list (array?) of user ID’s. So if I wanted the author page to include user1, then user2, then user 3, I’d put those in there. From there, I guess there’d need to be some type of loop where it would keep running a script for each user ID. Since I already have the code to style the user info, there’s no extra effort for that.

Would anyone be willing to help me out? Thanks in advance!
