you can only do chapter and full game runs, however, there is a individual chamber website. https://board.portal2.sr/ if you mean a single chapter run, just click the leaderboards button, click the submit run button, then put the link of the youtube video, time, and submit it.
yeah board.portal2.sr is for challenge mode but only top 200 times are displayed there and if you get top 200 times in challenge mode it automatically updates if you're signed in with steam (only top 100 times require video or demos i think) edit: now top 500 are displayed and top 200 need proof
The Challenge Mode leaderboards have changed to top 500 as of yesterday!
From now on, for top 50 times, both partners must submit their demos. As such, it will also be required for to submit any .vpks that are used during the runs. If you have any questions, you can join our discord @ discord.gg/p2sr or you can create a forum post here.
