Hello.

Before I made a tutorial on how to submit a run for a character that was not on the board, since Speedrun.com's recent changes this is no longer possible, please follow these steps to get new characters added to the board:

1. Click Submit run
2. Enter category as usual
3. Keep character as "Dropdown for characters"
4. Enter time as usual, if you're submitting an Individual Level speedrun then only use the In-Game time field
5. For video if your run is RTA then please provide a link to this and ensure the run is done in Marathon Mode with In-Game time selected. If you cannot do this you need the custom game data found here
6. If your mod is an older version of a mod please select "Legacy" under the mod version, otherwise keep this the same
7. If your run is an individual level then please provide the link to your .lmp replay file, if you cannot get into Record Attack because the game is saying that it is modified then revert to step 5
8. Regardless of what run it is, submit the master board link to your character and the version (if it is an older version).
9. Click submit :)

Hopefully that helps, ideally you'd just add the character yourself but that has been changed for the worst :C
