How should I introduce my service?

I am the developer of a learning app called NTPoker.

According to the terms of service, it is necessary to obtain permission from the administrator when making a post to introduce a service on the forum. Could you please let me know how I can contact the administrator? Additionally, if there are any other points I should be aware of regarding the post, I would appreciate it if you could inform me. Thank you in advance for your assistance.
