How to hack this website

Ive already ebedded the code, all you have to do is write
html
body
Your message here(feel free to pt more tags in)
/body
/html
And then press Ctrl+w 3 to 10 times (there should be a reactions)

It tranferres directly to the front page.

Put these signs <, >(lagerthan and smaller than) before the tags(body, html, /body, /html) as the forum might filters mine.
