mastadon...
I was posting events on there for a while. I think reddit is fantastic and had some effort been put in years ago to get it 'up and running' so to speak, I think it could've been a very beneficial resource and recruitment tool for AH. I talked to Skuzzy about it years ago and I believe he had told me he didn't really like the concept saying it was a 'cesspool'. Which I started thinking...have you seen the O'Club??
If you want to hype AH on reddit you might mention it on the hoggit group. Focused on DCS and BMS but not restricted. 91K members.
