Used the wiki perk today for the first time and was hoping that by changing the topic to a wiki not only would it be editable by everyone with TL1+ but that it would not be a discussion and instead be one entry with a history of changes. Being a StackOverflow user AFAIK all topics are one entry and all changes are kept as history. Now obviously a productive discussion can not take place in one entry, so the discussion would be moved to a linked topic that works as current topics. The purpose of this is so that once a wiki is done, a link can be made to it from other sites and those using the link would not see the discussion. Think Wikipedia with pages for topics and separate linked pages for discussion.
Request - One entry with history:
Either change the way a wiki works or create a new variant of a wiki, (new name or added property) such that it is only one entry and all changes are recorded as history for roll-back.
Request - Separate topic for discussion.
When the wiki with one entry with history is created, a second topic to discuss the wiki is created and linked to the wiki to keep the discussion out of the wiki.
