I am not the OP from which you quoted, but I am the OP of the question and please remember I am newbie with discourse so bear with me.
Since discourse site noted (SWI-Prolog) is new we don’t have many users and only 4 of us have the wiki privileges, me being the only non-admin and only user to reach TL 3. So I came up with this idea.
… to start creating topics that are wiki so that the users here can cooperatively edit the content, and when the wiki topic is created a second topic is posted to discuss the wiki topic to keep it clean. When the wiki is satisfactory, the links can be posted.
Since our Wiki Category is what I decided it should be, there is no reason for anyone to post a reply to a Wiki Category (example) as the replies will go to a separate and linked discussion topic (example); which was given the Category Wiki and subcategory Discussion, but I think that should be changed if the entire Wiki category is modified to not allow responses. Live and learn. So I take it that @pfaffman was trying to simplify things based on this knowledge. He made that recommendation before we added the Wiki classifications.
If any of this is wrong, please let me know so that I can learn and enjoy.
