Well to monetize your post, you need to be at least attain a Full Member status and participate in a Signature Campaign. There are different rates and terms in a signature campaign, and it's up to your judgment what signature campaign will you take part on. In any case, you should actively participate in discussions and refrain from spamming (as most of the signature campaigns discourage spamming and will not pay their members who spam a lot) because it is against the rules and regulations of the forum.

It will take some time before you could start earning from posting. For now, participate actively on the discussions and be active on the forum to rank up.
