Codeforces is one of our favorite platforms for contests and training, but it still has some annoying bugs. I recently discovered one of them. Since I couldn’t find an official bug report system (why doesn’t it exist?), I decided to write about it here.

When you try to register for a virtual contest as a team, the system does not allow registration if the team has four or more members and this is the expected behavior.

However, there is a way to bypass this unintentionally. For that, first register virtual participation with 3 or less team members. Then change the contest start time through the right sidebar — simply click on the time of contest in the "Recent virt. contests" sidebar and adjust it. Like here:

Now, for some reason, you will start your participation with the entire team.

This has happened several times to us and it is frustruating (definitely not because I can't see my handle). Please, fix it.
