Forum:Permissions / Power Help

Hey, I am currently running a private Tekkit server with a few of my friends, and am encountering a few issues I would like to see if you could help me with. First, when creating any type of power plant (solar, nuclear, geothermal, etc) it will generate power to the first and second MFSU fine, but after that, no power. I'm trying to build the plant on the outskirts of a town, and then carry the power through "powerlines" to the city, but it never reaches it. I have the MFSU's spaced 8-10 blocks apart, with fibre cable going between each set. What am I doing wrong, and how can I fix that? If you need pictures / examples of what I'm doing, let me know.

Second issue - bukkit permissions. I am trying to run Towny, Essentials, and Group Manager with my Tekkit server. Towny and Essentials works fine, however I can't figure out how to setup permissions with Group Manager for Tekkit (I know how to set up permissions for non-tekkit plugins). Where can I find a list of all permissions for Tekkit, and / or how do I set them up? Also would any of the above mentioned plugins be the reason why a Quarry and crafting tekkit items will not work, and how do I fix it?

Sorry for the wall of text, but just trying to get some help. Thanks.
