Noobs are not trusted users on this forum. You have to prove yourself by posting to other topics and ranking up with good quality posts. This will make sure you do not scam others with bad post qualities. To proving yourself is the strategy to get into signature campaign. After all signature campaigns will invest a lot money into you, trusting you that your work will represent them in the forum.

Anyway with the time you will get higher ranking and will be able to join the campaigns. As if now I can see you are already become Jr. Member because you are posting and making sure your account is "Active".  Now you will find opportunities too. All the best.
