Nice, I would be interested in helping as well. Perhaps you could open a launchpad project or something? We are planning a new web app using GWT (Google Web Toolkit) as frontend. We already have an application written in Django that spits json to a GWT interface and we are planning a new app based on zope3 (yeah, I did not like django that much, perhaps I should write about this when I get to know zope3 more...) -- Gustavo Matheus Rahal IBM Linux Technology Center _______________________________________________ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
