Paint cannons. Not for hitting people, for hitting Roids, to mark for referance when mining, so as no to have to go mucking about looking for that one Pyronic roid.
Comments!

Been suggested in various forms :/ Roid marking, I mean. We all want it, though.

Yea, I want to mark a few well known roids with:
*Teh Ninny was here!*

Nothing visible, electronic navigation system should handle it.

the simplest idea is to add the roid to your group.

then the roid would be highly visible in the radar, and allowing others in that group to locate it too.

and as a result of grouping, the roid would have to be found again, if the group disbands.
