Possibly a repeat question, but I'm not about to necro an post from ancient times. A run for a new game was recently accepted that is part of a series listed on this site. I'm not sure how to add this game to the series- there is a button for "add new game", but it seems to be specifically for adding a new game to the site rather than adding to the series. It's been so long since I added the games currently in the series that I forgot how I did it in the first place.

Specific info: game: https://www.speedrun.com/tlc_coae series: https://www.speedrun.com/super_solvers

Only site staff can add existing games to a series. You can request them to do that here: https://www.speedrun.com/The_Site/thread/5twus
