[Qgis-psc] Motion: move to GIT and Redmine

Thu Apr 7 13:27:51 PDT 2011

Hi Tim

Personally, I don't mind if we use git or svn, trac or redmine (so 0 in our 
voting system).
I only have few experience with git, but would be willing to catch up if the 
consensus is to switch.

Wouldn't it be better to concentrate on bugfixing and 1.7 release for now and 
do a migration after 1.7 is out? I'm just concerned that too many new things 
at once could create unforeseen problems.

Regards,
Marco
