No if you've disable reps I don't think you can spread them. I'm not sure. I know you can't receive them obviously but it would be stupid if you could bad rep people without having to worry about others returning the favour.
Grey reps are from newbies.
To me the reps are just if I see something hilarious, or a quick way of replying to something that doesn't require a PM.
Just watched first episode of Vikings. A bit low budget, and no nudity or bucketload of blood but interesting.
("History channel" logo dont fool you, Its actual tv drama not some docu thing.)
I traveled all of them as I pleased. I walked worlds of smoke and half-truths, intangible. Worlds of torment and of unnamable beauty. Opaline towers as high as small moons. Glaciers that rippled with insensate lust. And one world with nothing but shrimp. I tired of that one quickly.
