It's all up and running (As far as I can tell from single player...) I can upload Pokemon perfectly. Can't really check looking for one and trading yet though. If you want to you should download and install the latest version of the script then I'll give you the link to use for the URL.
I'm not sure how that would effect it. You're game should work fine, but if anyone puts up a delta pokemon and someone from my game trades for it it would be an issue. You could add the deltas and special Pokemon to the BLACKLIST array to fix that though. Once he get's back to me and it's set up I'll send you the link to put in the script and we can test it out.
Since I still have no mysql or online knowledge I wasn't going to, but hansiec is being an amazing person and setting me up a server so yes! Are you thinking of doing a shared server between our games?
