Hi, I am working on this in my free time

The project is very much alive and not abandoned. Regarding marketing of it, I absolutely agree. I'd be open to collaborations in this area!
Are you serious? What does working free time mean? Unless you are fully active on the forum and support forum gamblers, I don't think you can draw attention from the gamblers here. If you aren't regular on your announcement thread, then how do I believe you will help users to solve an issue in case something happens? I am not sure how your support system works fast, but in the end, forum gamblers will raise issues on your announcement thread.
You need to be serious about what you are working for. If you can't draw attention from gamblers, then your plan went wrong. You must have some strategies to onboard gamblers. Yet I haven't noticed something like this to attract gamblers. You should know better how to spread the word about your new gambling platform.
