Someone needed to write 1000 forum posts relating to music only.
Comments should be thought-out and at least a few sentences. Use at least 4 different usernames and post under each at least daily. The forum relates to music, celebrities, and general topics of the day.
You should also be willing to go to external links and build community with others and invite them to join and post at the forum. Meaning, post on other forums with either the forum link in your signature or post the url of the forum. This should be documented.
