Advised by International Advisory Boards, we use OpenConf to build our online website. But review chair didn’t know about it until we close the paper submittion. Then the review process delayed starting until the technical support between Japan and USA made.

Technical support volunteers was also asked to customize OpenConf in a week during the closing submissions and starting reviews, and some of the requires are rejected for lack of test period.

By the way, OpenConf requires several information before downloading, and redistribution of source code is permitted. So other real “free software” package may be suitable for the people who work with user/developer community.
