Open Source Community Building -- Lessons Learned
General
Written by Karl Wunderlich   
Monday, 08 September 2008 14:30

Now available for download, these slides cover lessons learned in two open source research community development efforts in the traffic modeling and simulation domain: TRANSIMS and NGSIM. Although different types of federally-sponosored open source research communities, one can draw several similar observations regarding the two communities. The slides address fundamental issues for both communities ranging from motivating participation, maintaining infrastructure, and adapting for self-governance.

Web Site gets a new menu to improve navigation

In an effort to keep improving the web site’s functionality and flow we have introduced a new menu to allow you to quickly access the following key areas of the site: forums, wiki, bug tracker and home page. Now moving between these areas of the site can easily be done by clicking one the links in the header of any of the pages. No more having to go back to the main page to select a different part of the site. This new menu also removes the need for a 2nd slider bar on long pages and allows users to bookmark pages directly instead of just the section home page.

We hope you like the new menu and if there is any way we can improve the site more please let us know.
