I know I don't post to much, I admit I never got into it. I rarely go online in general, But I seen a few posts lately regarding people commenting and giving criticism and feedback on people's builds, I know some people like to receive this as it helps you improve, and others don't,
I suggest making a new section in the forums called "Brutal Honesty - Critique Centre"
A forum for constructive criticism, be honest and helpful, Warning! To post your works in here you must be able to handle the criticism.
That way only those who want to be critiqued can post there. Problems solved..? I see this type of section on forums of military and figure painting sites where some can be very nit picky lol
