I looked at @FrostySR profile and I saw that he was in a team called Frosty Squad. How can you make a team?

At the bottom of info

The Frosty Squad team https://www.speedrun.com/frosty_squad

Bump cus I wanna know as well

It used to be tied to marathons but apparently it no longer is so i dont fucking know lol rules what are those

As far as I know, it's some kind of older feature that's just not being used right now. I heard they don't take requests for teams anymore, but that was a few months ago, so maybe it's changed.

You can join teams here: https://speedrun.com/teams

@Tutterey correction - you can only see the exist teams on this link.
