It is much much easier to remember it; On DarkRO where we had roughly another 12~ GMs, we all would make a list of the warps we added via @warp (just so we could remember the location of the warp).
I agree with Brian's method: @addwarp <map name> <x coord> <y coord> <name>
It is MUCH easier to type in:
@unloadnpc map1
@unloadnpc map2
@unloadnpc map3
@unloadnpc map4
@unloadnpc map5
@unloadnpc map6
@unloadnpc map7
Then it is to go to all those locations just so we can right-click remove them.
