We resolved some issues:

• People in the "Members," "Admins," and "Owners" groups can now go into the nether at will. The command /world will bring you to the spawn point inside or outside the nether...depending on which you're currently in.
• For a while, only ops could place liquids. I think we have that ironed out.
• Permissions should be tied to op/non-op, and they were. I think I've fully untangled them, and permissions should now be FULLY working correctly. Let me know if there are any command issues left, I'll fix 'em.
