How To Use Modding Queues:
How do I request mods?
Do not create a new thread for your mod request!
When requesting mods, you need to reply in threads created by other users. Every modding queue is handled in a slightly different way depending on its creator though, so you'll need to be careful and check a few things before posting.
First, look at a modding queue's initial post. This will detail some basic rules for the entire thread, such as what game mode or what genres of songs the creator wants to mod. See this modding queue's first post as an example.
Next, check the latest post by the queue's creator in its thread. This will often say "open" or "closed" and potentially list any extra rules not explained in the first post.
