Right... I'm having an inarticulate moment, it seems. I take the TT&T section as being more general, in the sense of say "hey, anyone got any suggestions on how I can make an effective cast-metal look for armour models?", whereas this seems to me to be more like, "taking inspiration from the EA-6 and the EA-18, I'd like to build an EA-14. I've thought of this and this and this, but ..."
...now that I think of it, that could be just as well suited for a TT&T thread. How would this new (sub)forum differ from the existing one, then?
