Please, apply on the Clan Recruitment sub-forum (you can find it on the Clan Discussion board).
But i recommend you to play a bit more since you're only an orange belt.
Just keep playing until you get at least brown belt and try to apply on a decent clan.

do u know any

Any decent clan? Well yeah (Obey, Origin, Spectators, these are really picky). But that's something you have to choose dude.

http://forum.toribash.com/clan_list.php Here you go Look For clan you want
(Ctrl+F) and write the name of the clan and search for it it will be shaded.

Tip: Don't choose afk or Nitro tho.
