I've recently created a problem in Polygon and added it to a Mashup. I know that Mashups can't be made public, but is there at least a way to share them with my friends? I'm working on educating younger coders and making problems for them to play with about things we're learning is very attractive to me.
You must create a Group. There you can create private contests for you and your friends using problems from cf and polygon. To create a group you must be in div 1 though
That seems a little bit restrictive. I live in the States, and all of the CodeForces rounds occur while I'm in school, so I don't have an opportunity to work on them, and when I do, my time is cut very short, so my rating suffers. I wonder if there is a special way to use Mashups without Div 1?
