PHP Based Online Math Editor and Database- repost

HI All, Based on feedback and clarifications from a lot of fellow freelancers, I am re-posting the project with more details. Also thanks to the freelancers who helped me with the choice of technology, I am putting specifics of what to use I want to develop using PHP an online Math Editor that can help me create, save and edit math problems (that will include text, diagrams and equations).... Each problem created should be saved in a MySQL database from where I can select, open (in the editor) review and edit question details. I should also be able to run a query, select some questions and export them to MS Word (one question per page) where the data type remains the same as in the editor: meaning text goes as text, diagrams go as jpg images and equations go as equation images... I should be able to copy diagrams (like geometry figures and graphs) from other applications and paste them anywhere on my page where I am creating the question This editor will need to use MathFlow Equation Editor as a plugin. [login to view URL] and [login to view URL]) Database: For the questions to go into the database, we will add several tags to every question (to be defined later) We will add fields to our database in the future and it must cater to that. To that extent, I need the data model to be properly defined and also followed. The tagging and query interface will need to be designed and will need to be a smart search and tagging to enable easy usage. Administrator: Have an overall control of the website. Allow access to people using a login and password, remove access of people, allow people to search and edit questions. The ability to export to MS Word will only be with the super administrator... The homepage will be simple with a high level dashboard about the questions in the database and basic features like login, forgto password etc. after loggin in, the person will have their own high level dashboard and links to create question, retrieve questions, edit questions etc. (All these things will need to be decided and agreed with your help) Note: 1. I will arrange for the hosting and also the SDK cost for the MathFlow plugin... 2. I will add more details to the specifications as we progress.. It is time critical and I will need many milestones and iterative development approach to ensure that we do it fast and remove bugs/ get feedback into the design very quickly and prevent rework...
