IRC devel meeting

by Daniel-Constantin Mierla

Hello, I would like to schedule an IRC meeting to discuss about the development of the project in 2012. The topics coming in my mind at this moment: - roadmap to next major release v3.3.0 - outstanding issues at this time, if any - packaging - ways to automate the process better - documentation - suggestions to improve it and attract more contributions in this field - ideas for new features - administration - web site, mailing lists, etc ... do we miss some good resource out there that should be added in the eco-system? Please add your suggestions for agenda to the wiki page: * http://www.kamailio.org/wiki/devel/irc-meetings/2012a I proposed two dates (Jan 26 and Jan 31, 15:00GMT) and made a Doodle poll for it: * http://www.doodle.com/qzteweb62sqax5r6 If you wish other options for dates, let me know. Based on results, we will announce the final date. Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com http://linkedin.com/in/miconda -- http://twitter.com/miconda
