Can you please tell me who can help with posting such posts?
What kind of post? Are you pertaining to the OP of this thread that contains images to showcase the casino feature?
If you are interested on my assumption above. You need to rank up at least jr. member to post an image here in forum since image post of yours as newbie and brand new member will automatically turn your image post into link.
But you can purchase copper membership to skip the ranking part and get immediately the benefits of higher rank member here. You can purchase copper membership here

TheWhyKingz if you're referring to the OP and want to create your own thread like that, you can hire someone to do it for you. Just provide them with instructions and they can make the post. However, if you prefer to do it yourself you'll need to rank up to Jr. Member and wait for 14 days if I'm not mistaken. Or you can follow Wapfika's suggestion and purchase copper memberships in this forum.
