If I remember correctly, Dan was pretty angry at the admins of AVSim and ended up leaving here because he didn't agree with the way Tom and other moderators managed the forums. As Kyle mentioned, he started his own forum at dantrix.net, but it was shutdown after some time. Looks like he's providing computer services now. His website is active again as a computer service shop or somthing similar. He was a nice guy...

a great option but its pmdg its a precision developpement
