Subject Re: 540 in perspective -- Re: [VOTE] Accept the proposed patch of CLEREZZA-540
Date Wed, 08 Jun 2011 11:02:18 GMT
Dear Henry,

The current situation is really annoying and part of the blame goes on me as
I'm part of the Clerezza community that failed to introduce you to the
project and the community in a way that empowers you to identify issues
suitable for an iterative development that leads to the envisaged viral
social web platform and to provide resolutions for these issues capable of

The current is the worst crises of our community and the biggest impediment
to productive work we have had till now. So I urge to collaborate with the
following approach to get back to productive work (i.e. getting issues
closed rather than arguing):

- you withdraw your -1 against a patch that doesn't change the behaviour of
any existing method and which has had 5 +1

- I will give hand to find ways to identify useful issues and solutions for
the desired functionality. You specify the issue you'd like to address and
I'll help you split this up into actually resolvable (and reviewable) issues
and describe approaches on how this be resolved. Then you'll be able to
contribute to a monotonic growth of closed (tiny) issues and thus to a
constant improvement of clerezza.

Please Henry, help leaving the current mess behind and get back to a
collaboration that yields to product improvements.
