  • The "web pages" module lets you restrict access, on a page-by-page basis, to whichever group or individuals you prefer. This is something I have been seeking for many years now. (Also, unlike posts, you can change the access after posting.)
  • It also supports multiple markup formats, including BBCode (same as posting), raw HTML, and something called PDL. I have no idea how to do PDL markup; as near as I can tell, it's this, which looks like it could be any number of formats. Which one is Hubzilla referring to? Is there some kind of <!DOCTYPE>-like markup to let you choose?
  • The "wiki pages" module isn't really a full-featured wiki (not that I expected it would be); you have to manually create the pages you link to, rather than links to nonexisting pages allowing you to create them automatically. It does, however, support font sizes, and keeps an edit history. (I don't know if there's a syntax guide anywhere, or if the syntax goes beyond header-size and [[links]].)
  • Hubzilla's BBCode supports bulleted lists and tables but not (as far as I can tell) font size, font color, or numbered lists. (I'm not sure there's a syntax guide for the BBCode either, but at least buttons and pop-up hints are provided for that.)
  • In BBCode content, when you insert a link using the button, a preview is generated -- and you can edit the preview (this is good).

Page description language - Wikipedia
In digital printing a page description language (PDL) is a computer language that describes the appearance of a printed page in a higher level than an actual output bitmap. An overlapping term is printer control language, which includes Hewlett-Packard's Printer Command Language (PCL). PostScript is one of the most noted page description languages....
