Antar, that was only one reason. I didn't actually know that PO had BW2 changes up, because I have been out all day. But also, as this user above said, PS only has BW, while PO has nearly all regions, and PO is a completely finished program. Also, BW2 changes are thing we won't fully understand till the English version is out, so it doesn't matter as much. As for your problem of not having high enough programming skills, why didn't you ask a user such as Zarel/aesoft or bmelts to help you, as this would have made your 'job' much easier. The way I can see this going is that Smogon will only have PS as their simulator, and if that's the case, I may as well just quit Smogon, because I refuse to use PS. And yes, I have tried PS, and within two minutes I immediately disliked it, you can ask Rory. That is all.
EDIT: PO does have RBY in their new server, so they have every region, on a completed program.
