If you'd like to help I'm very open to the offer, and to teaching you anything I can help with.
The main things that need working on are probably;
- Resources on the map, massive slog but doable
- Building trees
- Text and descriptions
There's other more complex stuff too... drop me a PM at some point, though bear in mind that I'll be away over the next week. If you want to make a start, just tinker with things to find out what they do, that's the main thing really.
And, of course, welcome and make yourself at home.
