List Site Contributors on a Page

There is a List Site Contributors plugin that is available only for previous versions of WordPress. Does anybody know how I can do this in the current version. I’m looking for a plug-in because I don’t know PHP.

If there isn’t a plug-in I’d be capable of following directions for placing a function on a page or in file and then calling the function. However, so far my experiments with that–within and –have been interpreted by WordPress as being text. Sigh!

Thanks.
