In the past, you could spectate in parkour, in city, by clicking on signs at /warp city. Spectating makes it so your avatar becomes translucent, so players can slightly see spectators without being disturbed. This would be cool, if for example, players have issues with a part of parkour and need guidance, or if they’re simply too lazy to parkour and just want to chat. There shoud be a confirmation before the spectator can join the player in a parkour race. This wasn’t fully thought through, as the idea just came to me while I was struggling in Flower Parkour, but hey, @LordInateur, I filed a suggestion.
