Question: How to remove a post?

I accidentally made a double post for my piece "You Know It's True" and can't find a way to delete one of them.

All I can do is edit and or delete an uploaded file. Does anyone know how to delete an entire posting by the one who posted it?

I don't know the answer, but try sending a message to one of the administrators.  They don't always go through all the forums.  Look under 'Staff'..    Chopin is one administrator. They should know. 

Done.
