1. Type your comment in the big, white box spacey-thing
2. Underneath said big, white box spacey-thing, there are words. They say, "COMMENT AS:" Click the drop-down menu and select ANONYMOUS if you don't have a profile
3. Click "POST COMMENT", or "PREVIEW" if you're not feeling bold enough
Thorough enough?
