For your consideration.
Why have the gamesas forums become so desolate. because of a lack of updates and contact from the developers. The reason the forum is needed is to keep up brand awareness for gamesas, if you have fans on the forums then you can guarantee that you have a market to sell games to, it also helps with interest in your products. This is why a community manager is needed that you can give news to fans to generate hype (With more hype you could easily have a successful Kickstarter) also the hype would help with sales of the games. The community manager would also manage the social media sites. Awareness could also be raised by doing raffles for prizes such as game codes. This is probably the only way I could see the forums being resurrected.

Thank you for your time.
