We should in general point to our own pages; in particular to gnupg.org/faq/somepage
When I greped for links to the FSF page (grep with string "fsf" I found out that there is one link to https://emailselfdefense.fsf.org/en/infographic.html in line 722 of src/ribbon-callbacks.cpp. Is that the link that was meant?
There are two other places where http://fsf.org/ is linked and some files with email addresses containing fsf but nothing else.
Because I'm just starting with GpgOL: Are we talking about adding links in the "Configure GpgOL" window or are there any other windows? If that is the right window maybe we could add a new tab "FAQ" and add the links there. At first I thought the links could be added to the tab "GpgOL" but there are already many entries and the other tabs don't fit well.
