I'm still working ony mine as much as my free time permits me. I also have a few other ideas for articles (Handling Savegames, Making GUI components, Making proper code structure for games - using gamestates).
If anyone is interested in any of theese ideas go ahed. I only reserve an article about svegames for myself since I plan it to be somehow conected with my current article and since thisone won't be so buig I expect to finish it quite quickly.

Anywhay I think that it would be verry nice if we have all these articles writen before the next PGD chalange since they might all come verry handy for some newbie game developers.
