Bukkit

The server I am currently making uses a lot of trees, for the time being I have been placing wool cloth as markers to later be replaced with saplings. This is one of the only mods that is current that can change the grow time for trees, the only problem  is that if I use MCedit or Worldedit to replace the wool with saplings and mod does not take affect. I would have to manually go around replacing each wool with a sapling. It would be nice just to have as an option or a command to generate all existing saplings.

Thanks
