Location app?

[Windshadow]

If there is a way to record a location in terms of its map name and X Y coordinates I have not yet found it.

The usage would be to record resource nodes for future use, to let a guild buddy know the loc of a node of something needed for a quest or perhaps a meeting point.

Or once you find a resource node you record it with the icon fo it on your copy of the map for that sector so you can find it again if coordinates don't work.

Also to record the exact loc of skyshards again to help others in your guild and all the other useful things that the gatherer addon in wow does

Just wondering
