I think I actually have some biomes O' plenty somewhere that i could give you, but not on the computer I currently am using.
That'd be nice!
You're probably right, I'll look at them and if they fit what I'm doing I'll had them to the next version.Bibliocraft and Buildcraft are both finished, so it'd be easier to use those.
And I also think they wouldn't mind you using their mod textures, it is an open mod support thread.
