I can't get into Molten Core.
If you're attuned, just talk to this NPC and he'll port you in.
It's easy enough to get attuned (just grab the quest from the elf and make your way to the portal inside brd and grab the quest item from the rock outcropping to the left of it), but, you'll want to leave yourself a path to walk out (ie, go through the room of the seven instead of just jumping in the lava and swimming) if you can't get yourself a quick raid group to enter through the portal inside brd.
