Using Checkio in class

Hello,

I am teaching a university course in Python this semester and would like to get all of my students involved in Checkio.

Is there an easy way for me to follow them all? In particular, how can I do a search for them based on their username, so that I can follow them? I realize that I can instruct all of them to just follow me and then I should be able to view all their profiles as a backup plan...

Any other tips or advice you have would be great!

Thanks, Daniel
