I haven't looked into the content of the site yet, but I recommend hiring a manager who can manage the announcement. This way it comes across as simple and cheap. Players are very critical, this way you run the risk that players choose not to visit the site because the announcement looks too simple. I assume they are new to the forum, so I think they still have every chance to make a nice project out of it. Has anyone played on the site yet?
Most of the established and reputable casinos in the forum today started on a similar note with ops, so I will like us to be friendly with ops and try to share our feedback and suggestion in a way that will motivate them to stay and build their presence on this forum.
You have suggested rightly for them to hire a professional manager to manage their presence on the forum but as a new casino, there can start by managing themselves for now but should update the thread with all the necessary information as suggested by other users here.
