After writing two tutorials in as many days, I thought that I might as well do them up 'all pretty like' and share with the community as large.
This is the first one I did; A quick introduction to how GCs are coded, and a tutorial on adding Hero spawns to them using the fan favourites Mara Jade and Kyle Katarn.
While there is certainly nothing advanced going on here, it provides, I think, a good starting point to people who have never touched the GC hero spawns, or GCs at all for that matter.
I can't get the PDF thanks for the broken tutorial...
