The nature of the wiki allows for anyone to create or update the content within it. This collaborative aspect is its primary goal.
Secondary to that, there is also a "reply" feature for every page where some communication may take place in the short-term, such as to query a piece of information or request a little more info.
In order to keep the wiki focused on page content and to avoid the need for readers to contextualise content, replies and chronology, replies will occasionally be move to this locked archive.
For discussion of a more detailed nature, the Egosoft forum would generally be a more appropriate venue.
