Hey everyone! Last week, I launched Codeforces Custom Contests, a Chrome extension (now on Firefox too) to instantly create personalized contests. I just wanted to thank you all for your support as there are over 300 new users in just one week!

Summary for New Users: Create custom contests instantly and analyze your results to efficiently train and improve your rating! See more info in the previous post

I’ve incorporated feedback and suggestions on the previous post and shipped a major update. Here’s the details!
