I like Curtis's Faith's material, but in fairness, he didnt exactly contribute a great deal to T2W, so its no surprse he's not missed really. I'm sure the unfounded slurs on his reputation from that other Turtle creature who spams here from time to time didnt give Mr Faith much cause to treat TW2 favourably.
Leaving the inhabitants of a much smaller (and far superior) trading site aside, why do you think people of the calibre of Mr Marcus no longer contribute here ?
You might argue that its the way of trading forums that people come and go, but almost without exception, the quality posters are still out there, and still assisting others, they just choose not to do it here (or the choice was made for them !).
