When submitting 2 or 3 player runs, is there any way to enter the other player(s)? I don't seem to have that option, but I really feel it's only fair to be able to share the credit.

You should be able to add multiple players now! ^^

/edit: Also added the players for one run that listed them in the description. If any other runners want their name added for a already verified run, post it here and ill change it!

Awesome! Thanks!

Can we add people even if they didn't particpate ? I will no do that but it is just a question

No, the whole point of the system is to see which people ran it, by doing that you wouldn't even know who ran it. But you are allowed to shoutout people in the description if you want.
