designpedia is here

An Open Source portal for sharing designs and plans for solutions and projects. These designs are for standard requirements and would includeUML, plans, tasks, estimations, ..etc. As well as other kinds of plans that covers life planning, careers, businesses and even children raising techniques and best practices. A project which will eventually end up to be the encyclopedia of designs. It will be implemented into several phases, starting with the platform then the parts, the tools ending with the portal itself.
