aianta on "How to write a "for" loop"

Hello,
I am working on a little project, basically what I would like to do is create a dynamic about page, which takes all users in a user group and print their biographies, names and a picture in a neat manner. My biggest issue is my unfamiliarity with PHP and the wordpressAPI.

I envision my loop working similarly to the posts loop however I am unsure of how to go about fetching this user data (what functions exist if any to do so, etc.)

Any guidance here would be highly appreciated.
