Right. A little guilt from me too. I come here daily, but keep forgetting to sign up for my Community Supporter account. Done now. Hope it helps.
Unfortunately, "Mechmancy II" is the only EN Publishing PDF on my wish list right now. I bought all the rest a while back. I'll see about picking that up too.
With the changes that RPG Now went through, does EN World currently get any kind of a benefit if I purchase non-EN World PDFs through "enworld.rpgnow.com"? If so, do I need to add them to my cart from that version of the site or just check out through that version?
