This is a part of a post I made elsewhere that possibly explains this: "Assisting the Silverlock Team": That's not their real name, it's just what I use to refer to Behippo and the others. Anyway, they've already got their own group, which presumably knows each other's strengths and have therefore most likely apportioned the coding to be done in the most efficient manner possible. Adding additional people would most likely slow the actual coding process down. This isn't my opinion, just what I've heard other people (who claim to code) elucidate. That's true only in case of production development process "for money". If we talk about some open source code (I know that SKSE isn't open source, I know, it's source available) you don't have to explain anything to anyone and anybody can jump into in matter of months. Even without any docs/comments. All you have to do is to look at final result and reject it if it's crap. I speak from my personal experience - I know C++ syntax but I haven't any real experience with it (I'm mostly Python programmer) but even I can understand what this code actually does and even hack into it a little bit. Of course I will make my stuff public only if I'll make something from scratch and of course my stuff won't be as efficient as their, but this is how people learn and something is better than nothing.
