Ages ago, we used to have a Wiki with modding information on it.
The wiki died, the information was outdated, but we saved it all in the "New Horizons Tutorials & History.pdf" file.
We do have a new wiki these days, but at the moment it is only used for storyline walkthroughs: http://www.piratewiki.net/index.php?title=New_Horizon_Quests .
I would love for people to make more use of it and try to build up a proper knowledge base.
Unfortunately, I have requested such many a time in the past and it just doesn't happen.
We've got a great bunch of people here, but sometimes when we want something done, I have to do it myself.
Of course, as you point out, that doesn't work with something as expansive as this.
If you want to help, what I would always recommend is just to play the game and see what you would like to change yourself.
These are a few things that I'd personally like to see worked on:
- Merging Pirate_KK's latest code base with the current Build 14 Beta 2.1 install;
this contains several fixes, improvements and the Customize Character interface addition for "Select Storyline at the start of the game
- Fixing the Capture Colonies Mod
- Finishing the Friendly Contact on High Seas (Hail Ship) mod
The code for this is in the modpack, but turned off on purpose because it isn't finished and doesn't quite work yet.
The person who worked on it has not been here for quite some time now.
The Graphic Anomalies Hylie Pistoff mentions are really annoying as well, but I wouldn't recommend that as your first project.
Many people have tried their best at it and while we managed to decrease it, we still haven't figured it out properly.
As such, it really is a shot in the dark and probably would be very frustrating to work on to start with.
But as Hylie says, the main thing is that you work on what you personally would like to work on.
If you don't, then it won't be fun for you and that won't do anyone any good.
