Steve, we don`t have planned this. Four years ago, we began to work on Air-Child. At this time we haven`t had a preverence for VATSIM or IVAO. Two years later, in September 2008 we made announcements in different forums (also in VATSIM and IVAO forums) that we are looking for beta testers. After some weeks, 95% of the new beta testers was comming or flying at the VATSIM network, and 5% at IVAO. So the current status of Air-Child is result of it`s history.
My opinion to fly on VATSIM has also something to do with history. I`m flying online since 1999. At this time VATSIM (former SATCO) was much bigger then IVAO. I also have tetstet IVAO often, But I found out that VATSIM controllers where more skilled. So it was much more funny to fly at a network with more and better controllers. If you are flying such a long time at one network, you will meet many gentle people and friends. So for me there is no discussion: If I`m flying online, I will fly on VATSIM.
But I know, that also on IVAO many, many gentle people are working.
Steve, I think that VATSIM is very user friendly. And there is no need to work on SB4 or SB3 (for FS9) at this moment. And if you are using our "File Plan to VATSIM" function, you only have to start SB3 or SB4, select your aircraft, enter your callsign and you are ready to go. Nothing is more easy then that.
But as I have said before: That is my personal opinion, but also the opinion from most of the Air-Child members yet. But we have allways open eys and ears for the suggestions of our members...
Best regards
Norbert
