If you have a problems or questions get help from the Ubuntu community. The maybe most advanced sites are Ubuntu Forums and Ask Ubuntu. Both provide question and answer services for Ubuntu users and developers. There you can 1. check whether there is already an answer to your problem and 2. ask a question if there is not. Usually the community will provide you with some suggestions or direct you to sites where you can find solutions. Of course you can also be of service to the community and provide answers to open questions.
