[CentralOH] Codesharing recommendations?

[Brian Long]

Hey all,

Long time lurker, first time poster here with a question. At an
enjoyable CentralOH Python lunch the other day, Jim suggested that I
put a question I've got to the larger community.

That is, I just finished a run of teaching an introductory Python
course in Columbus State's Workforce Development program. Things went
well overall, but I'm still looking for a good codesharing platform,
where students can work collaboratively on a particular challenge or
assignment. Things I've used in the past with another person or two
(codeshare.io) didn't work well when 5+ students were attempting to
collaborate (or even see their group's code). I'd prefer something
lightweight, but am open to whatever works.

Any suggestions or other things to look into?

Thanks,
Brian
