I'm sure the guy has been busy with life...these projects aren't streamlined productions, so there are delays. No need to stalk the dude.
If I was stalking him, I'd PM him a bunch of times, show up at his house, etc. etc. Or send some Germans for the Ark. I'm just interested, that's all. Usually, when I check the threads with no replies after months, I find that the OP hasn't been around either. In this case, I noted he'd been online recently, and thought it was odd that there wasn't an update to what is, in all respects, an epic build. Even a 'life has been kicking my butt' is more than helpful.
I also don't get why you're calling out people to finish their projects when you haven't even started yours...just saying.
Ouch, dude. Harsh.
If my Wife would let me start, I would start. Right now, cash is tough, and other projects are on the go. (I'd like at least ONE of my bathrooms to be 100% functional, personally.) I can, of course, plan and ramp up, and my home PC is all ready to go... So far. There's always stuff to do.
