Sorry if this has been asked before, my search didnt really bring up anything, I wanna make a new category, im gonna try it out later. How do i go about submitting it? Thanks in advance

thank you for getting back to me, i posted the description of the RTA and the run on the discord link you gave me, ive had interest from other runners when i tried it live, the routing i took was slower as im new to the game after 25 years break
