Hmmm, i am not shure, whether i am right here. Just want to tell about a possible improvement of the format for the table of contents. Talking about V9.2.1.
The level 4 headlines (eg 188.8.131.52) are shown with the same indentation as the level 2 headlines. This is somewhat confusing when reading through the TOC. Please indent the level 4 headlines so that they begin to the right of the level 3 headlines. It would also be more readable, if the headline number would not be part of the link, just as the level 3 headlines.
But nevertheless very good work.
Just a heads up that the upcoming 9.2 docs are changing to HTML format. A preview can be seen at newdoc.freenas.org and once there is a landing page for switching to previous docs, this wiki will be retired. For previous doc versions, use the PDF version which does have a better formatted ToC.
