Plan on being absent? Post it here. Just state when you're going to be gone and for how long. Putting a reason behind it is 100% up to you, but its never necessary!
This is where you post artwork, written projects such as stories, poems, etc, and anything else you want to share with the world! however, it must be YOURS. it's okay if it's a parody or work of fanfiction, but if any of it is traced to someone that you copied from, the piece will be taken off the site. Same goes for art.
