some errors I have noticed with the wiki parser on my own site that also does not work here:

heading

• google sometext:
  • double bullet point 1 ending with colon (the addtional sub text below this is missing):
    text preceeded by double plus signs blahblahblahblahblahblah blah blahblah blah blahblahblahblahblahblah blah blahblah blah blahblahblahblahblahblah blah blahblah blah blahblahblahblahblahblah blah blahblah blah blahblahblahblahblahblah blah blahblah blah blahblahblahblahblahblah blah blahblah blah blahblahblahblahblahblah blah blahblah blah
    sub text of double bullet point 1

• google the word google should be a link preceded by a bullet, also:
  • "double bullet point 2"
    "more text" this should be subtext of double bullet point 2

  this is text that should not be parsed 

showing

non-parsed does not work

however,

 showing ~np~ and  ~/np~ non-parsed does work
