SignGo is distributed as shareware. The essence of shareware is to provide you with software that you get to "try before you buy", while rewarding the efforts of the developers.

When you think about it, the opportunity to try before you buy is the ultimate guarantee of a product's quality and usefulness to you. In fact, shareware can be just as professionally developed as software that comes in a fancy box (with a lot of hype and yet no way to determine issues such as the "look and feel", etc.), but the price of shareware can be set lower because it does not have to cover expensive marketing costs.

Still, software businesses that market their products as shareware need to get paid for their efforts just as any other business. When you support the shareware concept, it ensures that the concept will continue to work and you will continue to get to "try before you buy". Thank you for understanding and honoring the "shareware" concept.
