In the near future, the in-game leaderboard will be returning for solo runs. From now on, if you submit a world record speedrun, make sure the FIRST thing in the description is your roblox user ID. You can find in your profile url, the long list of numbers. Then you can write whatever you want on the next line, or separated by a space. For example, if I submitted a WR speedrun, this is what the description would look like.

"25785634 [Rest of description]"

Or:

"25785634

[Rest of description]"

Happy speedrunning.
