When you need to build a web application you usually have some business functionality in mind but there is always a certain amount of web plumbing that needs to be implemented for things like navigation, authentication of users, security and roles and other things that are needed to support most kinds of business application logic.
After building many web applications you realize that a certain amount of this plumbing you are having to write over and over for each project. Most projects don not allocate much development time for these things and you end up doing things the quick way rather than the best way. Business stakeholders often can not be bothered with the technical details, they want to see results quickly and they tend to judge the success of the product/project by how attractive the user interface is. So the developers are really the only ones who are going to notice the elegant design of the plumbing and often enough little emphasis is put on the elegance of the design.
Many projects that don not spend time making sure the plumbing is elegant later find as the project grows in size the ugliness of the plumbing becomes more apparent and more difficult to put right because too many things are hard coded or cobbled together differently in different places. When projects get really messy, making small changes in one place end up causing unintended side effects or bugs in other places.
If you build on mojoPortal you are starting out with a core framework where great care has been put into making the plumbing elegant and efficient and easy to understand for the average .NET developer. It has been developed/managed by Joe Audette, MCSD, MCDBA, MCSE, under peer review provided by the open source community. Since this plumbing is already built for you, you don not have to spend any time developing it yourself so you can get quick results by starting right in on your specific application logic.
You can think of mojoPortal as a Starter Kit for Advanced ASP.NET Web Sites and Portals.
Out of the box, mojoPortal provides dynamic database driven web site(s) with an XHTML compliant Content Management System and community features like Blogs, Forums, Image Galleries, etc.
