[For new forums members only] Hide the ugly-red warning message [JS]

I like this forum's design but this ugly newbie message keeps bugging me.
Made a quick script to hide this message and make the website lookbeautiful.
I know it will go away after 15 posts but i still made this for others who might be interested in removing this alert warning like me.

Install it via tampermonkey extension for chrome and greasemonkey for firefox




This thread is a joke, i know this script is useless for almost everyone.i am just making this as anopportunityto showcase my little coding knowledge and contribute in a sarcastic way.
