Okay, I've finally gotten around to doing something I should have done two weeks ago, I've finally made a damn spread sheet to keep our navagation mesh interiors more organized.
The spread sheet works similar to the npc one, you can claim one cell, or 200, it's your choice. Also, if the cell you navmesh doesn't crash, just leave the "Any errors to report" block blank. After you're done your round of navmeshing , just save the esp and post it.

This will be the thread we talk about everything navmesh, everyone's favorite subject. Which reminds me, we still need someone to tweak up our exterior navmesh, one man cannot tweak up a whole world, so I figured we could do that by regions.
Here are some links about navmeshing, and what the hell navmeshing is exactly.

Also here a video guide on navmeshing by Bethesda(I think some of the other guides on navmeshing are a little better, but eh)
