Open archived version from archive - Community Discussion on 4 January | planetmath.org

a community discussion at 1 30 p m Eastern time on Saturday 4 January 2014 This will be the 14th year of PlanetMath s existence and during that time much has happened and changed both at PlanetMath and elsewhere Thus in preparing for another year one of the topics we may want to consider is the current state of affairs and our place in the scheme of things To help get the discussion started here are some questions to think and talk about How can we grow and sustain the PlanetMath community What other communities and websites related to free math are out there How can we connect to and collaborate with these communities How do we fit into the larger world of online mathematics and what roles can we play After the discussion we will have a workshop session where we will start implementing suggestions made in the course of the discussion ans well as make progress on other projects of interest to the participants We will use skype as a medium if you are interested in participating contact Joe Corneli Skype user name holtzermann17 or Raymond Puzio Skype user name rspuzio Search form Search Home Articles Questions Forums
