Well, first off all this stuff is foundational. You can't do anything unless you can do this type of stuff. It is a huge barrier to entry to have to spend 15 or 20 hours, at least, to find the info to do this basic stuff that an experienced person can do very very quickly.
Secondly, one of the big problems in M&B is lack of content. Now, I don't know if this is possible. But could you have 20, 30, 50 people make a variety of quests and encounters and fold them all into one mod? Would it be incredibly difficult if everyone sent the appropriate files to put 400 encounters/quests into a mod. I know it would take a while but would it take 2-3 minutes per encounter or an hour?
Because if it is fairly simple then you could have a lot of lesser modders taking these basic tools to build an encounter. Send the files off to a triage committee along with recommended level and the committee member plays the encounter and is maybe willing to make an easy fix or two if necessary. If the encounter makes the cut they fold them together and send sections of ten or so to the final person who sticks it into the random encounter section.
If it is closer to 3-5 minutes to fold in I'd be happy to make at least 10 encounters or quests (example, reach level 10 and the next merchant offers the quest.) And I would LOVE LOVE LOVE to see a bunch of random encounters folded into something like Band of Warriors.
Look at Oblivion. The map is dotted with shrines, many associated with quests or minimum requirements that lead essentially to dungeons. Once you have these tools, and maybe a resource pack with some shrine scene objects and/or zombies, ghosts, skeletons then you could have people like me put together lots of "dungeons" with associated quests fairly easily. And once you have the system going if someone like Yoshi deigns to contribute one then you know it will be an awesome one.
Just an idea but even if the hundreds of encounters idea isn't possible I would still like to see this basic tutorial put together. I'd almost certainly never make a big mod but I'd certainly be interested in putting together a quest line that takes you through an hour of play or two. Perhaps I'm wrong but it seems that that would be fairly simple with this basic info. If the mini-modder is a good story/dialog writer it would be lots of fun for the M&B community to play as a diversion.
