using the buildcraft diamond pipes i made a sorting system that was only about 6 blocks long, sorted all the items i got from a quary and teleported them to the right chest, teleport pipes on chests were in the back so you couldn't see them, and the sorting was done by diamond pipes in the ceiling(glass so you could see the items moving). adding onto it was as simple as adding another diamond pipe to the end, i had all my items sent to this machine and it sorted everything. now if i was to do the same with redpower it would be alot larger, harder to handle, and bottom line it just wouldn't look as nice.
but back to original question i had, is there anyway i can enable them again?
don't think i put it there but there's a config file in the buildcraft folder which apparently enables/disables teleport pipes o.O has them all enabled though...
