I've used all three versions, nomenu, basic, and full, and none of the plugins seem to work by itself.
The nomenu version shows no signs - at all. No errors, but no way to tell if it is working.

Both Full and Basic work with admin commands, spraytrace, adminspray, removespray.
However, there is a condition.
Both of those versions will only work if you use adminspray to spray a decal.
Then if you look at the spray, it shows who sprayed it.

If you do not use adminspray, looking at a decal will say
"No Spray were found on where you were looking at"
