So after stumbling upon this article:
http://1d4chan.org/wiki/Scraplootas I've become incredibly motivated to make a scraplootas army.
The army will consist of a LOT of grots, grot filled vehicles, walkers, and of course (once I've saved up) an orkified chaos titan.
I'm going to be posting progress and such for this endeavour as I go, though the first update probably won't be for a while.
Please post ideas, tips and really any relevant ramblings
