Hi!
I think Adams post draws it out pretty clear. This competition is open to a great deal of interpretation . That's mainly why I choose not to call it a competition (also I think the term 'quest' is a bit underrepresented in this forum).
In my opinion you'll mostly be competing with your self. Using a sand-box environment inside the Forum to set aside some of the sometimes work-like songwriting and be able to focus on more creative writing with the added opportunity of getting a substantial amount of feedback.
All the best,
Martin
