When do I need to buy an Umbraco license?

This may seem a slightly obvious/silly post but the answer is simple -it's just not *that* well documented/explained.

In a nutshell there are three scenarios you need to worry about:

• Using Umbraco in a non-commercial environment with the branding (logos etc) intact -no fee
• Using Umbraco in a commercial environment with the branding (logos etc) intact -no fee
• Using Umbraco in a commercial environment without the branding (logos etc) -fee

So there you have it. But to be fair, you should always pay for it if you're using it in a commercial environment just because it's a great product (and it's good for your karma!)
