Yes!
When the first person of a friend group signs up, they will have a box in the registration process that looks like this:
Simply put in your friend's name and email address and it will send them a sign-up link. If they sign up through that link, you will be attached in our system.
Any friends that you invite should sign up soon after receiving the link. If they sign-up after we start putting together the team, we may not be able to place them on any team.
There are very few circumstances where we may have to split a friend group. If we have to do so, we will contact you prior to see if you're still interested in playing separately.
