 ## Introduction
 
-This code of conduct governs how we behave in any OSGeo forum or event and whenever we will be judged by our actions. We expect it to be honored by everyone who participates in the OSGeo community formally or informally, or claims any affiliation with the OSGeo Foundation.

 Specific Guidelines
 
 We strive to:
 
 - Be open.
-    We invite anyone to participate in our community. We preferably use public methods of communication for project-related messages, unless discussing something sensitive. This applies to messages for help or project-related support, too; not only is a public support request much more likely to result in an answer to a question, it also makes sure that any inadvertent mistakes made by people answering will be more easily detected and corrected.

+  in an answer to a question, it also makes sure that any inadvertent mistakes
+  made by people answering will be more easily detected and corrected.
 
 - Be empathetic, welcoming, friendly, and patient.
-    We work together to resolve conflict, assume good intentions, and do our best to act in an empathetic fashion. We may all experience some frustration from time to time, but we do not allow frustration to turn into a personal attack. A community where people feel uncomfortable or threatened is not a productive one. Note that we have a multi-cultural, multi-lingual community and some of us are non-native speakers. We should be respectful when dealing with other community members as well as with people outside our community.

+  community members as well as with people outside our community.
 
 - Be collaborative.
-    Our work will be used by other people, and in turn we will depend on the work of others. When we make something for the benefit of OSGeo, we are willing to explain to others how it works, so that they can build on the work to make it even better. Any decision we make will affect users and colleagues, and we take those consequences seriously when making decisions.

 - Be inquisitive.
-    Nobody knows everything! Asking questions early avoids many problems later, so questions are encouraged, though they may be directed to the appropriate forum. Those who are asked should be responsive and helpful, within the context of our shared goal of improving OSGeo.

 - Be careful in the words that we choose.
-    Whether we are participating as professionals or volunteers, we value professionalism in all interactions, and take responsibility for our own speech. Be kind to others. Do not insult or put down other participants.

 - Be concise
-    Keep in mind that what you write once will be read by hundreds of persons. Writing a short email means people can understand the conversation as efficiently as possible. Short emails should always strive to be empathetic, welcoming, friendly and patient. When a long explanation is necessary, consider adding a summary.
 
-    Try to bring new ideas to a conversation so that each mail adds something unique to the thread, keeping in mind that the rest of the thread still contains the other messages with arguments that have already been made.

 - Step down considerately.
-    Members of every project come and go. When somebody leaves or disengages from the project they should tell people they are leaving and take the proper steps to ensure that others can pick up where they left off. In doing so, they should remain respectful of those who continue to participate in the project and should not misrepresent the project's goals or achievements. Likewise, community members should respect any individual's choice to leave the project.

-If you believe someone is breaking this code of conduct, you may reply to them, and point to this code of conduct. Such messages may be in public or in private, whatever is most appropriate.

Should there be difficulties in dealing with the situation, you may report your concerns to event staff, a forum leader or the OSGeo Board. Serious or persistent offenders may be expelled from the event or forum by event organizers or forum leaders.
