Has anyone tried both Redmine and Retrospectiva, and is able to make some comparison between the two?
I'm currently using Trac for my projects management and issue-tracking, but I'm looking to test some alternative and the above two seems most likely to fit my needs. I understand Redmine is more of a Trac clone, but Retrospectiva seem to support agile methodologies via a nice plugin (http://retrospectiva.org/wiki/AgilePM).
Any experience with any of those in comparison to Trac would be also beneficial, from the features, but also installation and management point of view - that's where Trac gets a bit complicated, I'm not familiar with Python and I run into problems when something breaks. So something that is stable by itself and the underlying platform and needs minor maintenance work is an advantage. What are your experiences with those?
