I'm with you, Pat. I want to do the same thing. Here is my plan so far:
Already became a wiki editor, which has helped me climb the learning curve. I see this is a way to prep for doing more for this project. Then started writing these holotapes which serve as in-game Help Files. I hand them out as i meet new characters.
Downloaded the Dialogue Editor and Mapper tools and dove into making maps. Hit a brick wall! Mapping is very slow, especially without templates. I heard from K-man himself about his revised Mapper tool (including his templates!) being released for Season 2, along with the enhanced F1 Help overlay feature. I DL'd the new client, witnessed how great is the new F1 feature and am now eagerly waiting to see the new mapper and templates. I look forward to writing Help Files.
Maybe we can team up to be like junior devs but i think we should wait for the new tools before going too far. You can however anytime DL the existing mapper and see it for yourself. It's not impossible to use - just very slow. Keep in touch.
