To add a link to an internal FAQ in the LON-CAPA User Help, do the following:

Type <faqomatic: file#> where you would like to inset the link. You can find the
file number of any page by looking at the bottom of the page your'e interested 
in. There will be a link that looks like this:
   This document is: http://help.loncapa.org/cgi-bin/fom?file=299
The file page number is the number that is listed after file= in the link. Replace
the text file# with the page number from the link. 
  Example: <faqomatic[] :299>

NOTE: Remove any spaces from the internal link. I had to add the space to keep the
example from translating into a link.
