The way to growing a great racing league is exposure & publicity, I have been thinking about this. Delta is currently streamed to the masses via YMTV but only from the point of view of the streamer, I don't have any problems with this but on both Mixer & Twitch you can create teams which allows viewers to switch between POVs. On Twitch, teams can only be created by a Twitch partnered streamer however on Mixer it only requires someone with 5,000 sparks.
The whole point of this post is that if you have a Xbox Live account, you have a Mixer account too (sign in with the same email & password as box Live). If someone in Delta has 5,000 sparks to create a Mixer team, they could create a Delta Mixer team & if everyone joined that team it would allow viewers to see all possible POVs from a Delta race.
Once again this is only an idea but it might be worth a trial run at least.
