For coaches who would like to branch out to multiple games it is difficult to avoid a big wall of text on the about page. It might be too much work on your end but being able to have one bio linked to one game and another bio linked to another game would be really cool for any coach wishing to reach a larger audience without pushing away clients from the other title.
Edit: I thought of a pretty simple solution to this, I think it would be awesome if we had coaching tabs for a coaches profile for different games so that the bios can be different and won't interfere with each other to create a giant wall of text. That way one tab can be linked to one game and the other to the other game so that students will always get redirected to the correct tab for the coach depending on which game they were searching for. I know this might be a bit niche since most coaches prioritize one game but personally I think it would be a fun addition.
