Okay, a couple questions regarding these shards. . .

Is there a way to tell when looking on the map if I have already touched a shard or not? I look at them on the map and I can't tell if that is one I touched already and is in my transport network?

Also, when I click on one to transport to, a list of locations comes up. . .how do I know which is which? Some of them are near nothing on the map so I have no idea if that's the one I want or not? For instance, I'm in New Gridania and there is a shard close to the Archers' Guild, but when I click on the shard it doesn't state Archers' Guild? So If I want to go to this location sometime I have no idea which shard location this is?

This is very confusing. . .I have no idea where I'm transporting half the time.
