Because that's so people can comment on the news posted on the "News" page. If you want to post news, go to the LP Chat forum and post in the "Got News?" thread. Also, in the future don't post in the Newbie Camp, if you want to ask questions go to the "FAQ" thread and ask there. Finally, this will be closed.
Only administrators can post in the news thread. If you want to suggest news, post in the got news thread in linkin park chat. This is in the wrong forum so like Uncle Raj said...post in the FAQ section if you have any questions.
