We are open to customize our need on your product.) Openmeetings is an open source software. The project requires to add following extra features on top of the software: 1. Use multiple "break out" rooms for students to work separately. 2. Quiz - Generate the own quiz. 3. Web page importing - type in the web address to import a web page for free annotation. 4. website integration - the web conferencing tool should be integrated into a PHP website for all the back end data accessing. (Many original functions from Openmeetings can be dropped.) If the work quality is satisfactory, you will get our full list of requirements as this is a huge project. In addition, we have many other independent projects needed to be done as soon as possible. This post is not only for the project, but more importantly allow us to find a high quality team or company to cooperate for all future projects, including long term maintenance. While bidding, please include estimated total cost, time, your email and Skype IDs. Thanks.
