Its my first time here, why cant I post my animation??? Every time I put down a link, it says I have to get approved please help!

becuz you is such a new member mods/admins have to approve your posts before they become public

it's some sort of anti spam system

As the origin said, it is anti spam system, once you make a post with a link in it you'll have to get a mod to approve it
Once you have 20 posts, you won't have to do that any more (please don't spam your way too 20 posts, nobody likes it when people do that)
