And i tried to find it but i cant, i know there's one in Colors or something but its not showing anything..

Hello,

Your site should automatically appear in google a few weeks after creation once the google bot has visited the forum.

Note: Google bot can only see sections that guests would see, that said, we recommend that you leave atleast 1 section or more of your forum viewable and readable to guests so that Google bot can properly index your forum .

You can also speed it up by sharing content on Google+.
