What does it take to be a GD? How can someone let you gd their map? Can you still gd a map even if it's ranked? I have read a forum about this but I'm still not entirely sure about how it works
this explains what a gd is and how people let others gd their maps but after mapping your gd you can send the .osu file (for your diff) through discord or the text in the file somewhere for the set's host to copy and paste. also you cant gd ranked maps.
