It can't be deleted or risk deleting posts/reviews made by other members, but nothing's going to happen to it if you leave it alone. I hope you come back though!
Just don't log back on, though we would hate for you to leave. If you don't want your posts in the literary forums then you can edit, erase the content, and leave some like "deleted" or "X" in its place.
I do hope you wish to return to us someday, though.
