Yes you can. Hit the little red and white triangle above each post made. You can write out a message and each moderator will see the post/thread in question and your message to why you think it should be removed/locked. And if it's breaking the rules we will remove it or do whatever is necessary to handle the situation.
Why did you laugh? You already did the silly thing 5 minutes before he said anything. Sorry, I am not getting this at all people.
I was laughing for at myself, then at the post, but the post is waht made me realize my mistake. I shouldn't have put 'Yeah' as the topic starter, but it was emphasis on the question. I wasn't answering it for myself. lol.
