I met with wagga and + @ti2d last night for pizza.  Wagga brought up the situation of people here ending up with spare slots due to friends dropping out.

He suggested that, you find yourself in that situation, and might be willing to share the slots with others, you might post here and invite people to join in with your group.  The decision to do that is entirely up to you.

The other alternative, and of course is quite commendable, is to call the Wilderness Permit number (760-873-2483) and release the empty slots from your reservation. That allows others to call in and reserve the permits for themselves.
