No other program, other than your browser, is needed to use GameDesignTech.
Millions of people sign up for sites every day. That means that others will sign up for mine to sooner or later.
Why not a site where you can invite other people to talk realtime about game design.
People have joined GameDesignTech and go there once in a while to see if there is anyone there. I am there all the time that I am not at work or otherwise distracted by life. I have had some really good chats there with quality people that share my passion for what we do. It just needs more people to use it, thats all.
Hope that it works that way so we can get something out of it.
