Probably ShadowMoses, iirc he was able to talk Xenus into releasing the sdk and he did the translations into English as well. His site was up from the release of BP until about 2 years ago, iirc.

There was a lot of mod content on his site and he used to post here (he's defiantly registered here) though not sure how long it's been since he posted. His was the only English site, if he hears about this maybe he can make all the mods available. Hopefully.

Good luck.
