Let's put it this way:
Once upon a time, there was a kindergarden named PasteSoft. It was a small kindergarden, but the kids of PasteSoft were full of weird ideas and full of passion about all the new technologies, languages and possibilities that the Web can bring, and they really wanted to share all this with others. So they decided to go around telling their ideas to other kids and felt pretty much good about themselves, until one day they realized that their passion was too huge and unorganized. Their little heads were just too small to keep all the plans and creativity in there. They just had to do something about it. And this is what they did...
They made a gang and named it the Red Leash Gang. Why red...??? And why Leash...??? Their amazing pets were always around them, and like a little gang, wearing their red leashes always watching them, which is the great name for our playroom. Makes it really like a big red leash to keep our ideas close to us.
Anyway, the RedLeashGang is like a big room to put everything inside and play with it. They say you can call it their playroom, coz this is what they do here - they play with their ideas, put them here and leave it opened. There are no locks, no keys not even a door. It is opened to everyone who finds it interesting. That means, anyone can join to play.
So now, go "PlayRoom" and you will understand.
