I visit GameProducer.net most days to read the insightful articles and to sometimes post my own comments. They have recently changed format from having a blog, where you can comment in normal blog-style, to having a related forum topic where you comment instead. I took me a few days to get round to registering with the forum but now I just tell it to “remember me” so it’s quicker to logon and comment.
The site regularly puts out useful articles covering all sorts of Game Producing topics from business techniques to philosophy and is well worth checking out. The forums seem to be pretty popular as well. There are also many optional extras on the site that may be worth investigating.
You can read more about it here.
