There isn't one for ACARS Decoder and some of our other products. This because we felt RadarBox was special product in terms of customers talking to each other about new aircraft scene, antennas etc.. that it was needed.
Also forums put a lot of pressure on us as well, just look at the amount of RB posts we need to read incase there is a support query in there, we would probally spend out live on the forum if we had others :)
