Just trying to figure out how to apply to be a moderator. Thank you

With an account that's minutes old, I would suggest focusing on speedrunning first and foremost before you try to jump into anything regarding moderation

If you want to moderate a game's leaderboard, you can talk to the current moderators of the game about it by opening up their profiles and sending them a direct message. Most likely they'll only accept your help if you're a runner of the game in question.

If you want to apply for any staff position on this site, you can do so at this link - https://www.speedrun.com/staffapplication
