 WikiLinks provide easy linking between pages of the wiki. To create a
-WikiLink, just put the name of the page to link to in double brackets. For
-examples "[[ WikiLink ]]" (without the added whitespace). 
+[[WikiLink]], just put the name of the page to link to in double brackets.
+For example "\[[WikiLink]]".
+
+If you ever need to write something like "\[[WikiLink]] without creating a
+wikilink, just prefix it with a "\", like "\\\\[[WikiLink]]".
 
 Note that there are some special [[SubPage/LinkingRules]] that come into
 play when linking between [[SubPage]]s.
 
 WikiLinks can be entered in any case you like, the page they link to is
 always lowercased.
+
+While a WikiLink is limited to alphanumerics and only a few special
+charaters, it is possible to create page names containing other characters:
+
+* To display a page name with a space in it, use "\_" in the WikiLink, for
+  example, "\[[Multi\_Word\_Page\_Name]]". 
+* For any other special character, you can use "\_\__nnnn_\_\_" where
+ _nnnn_ is the unicode character number. For example,
+  "\[[This\_page\_name\_is\_\_44\_\_\_uselessly\_\_44\_\_\_a\_complete\_sentence\_\_46\_\_]]"
+  Limiting use of this to when you really need it is a good idea.
+
+Note that if the file linked to by a WikiLink looks like an image, it will
+be displayed inline on the page.
+
+It's also possible to write a WikiLink that uses something other than the
+page name as the link text. For example "\[[foo|SandBox]]" links to the
+SandBox page, but the link will appear like this: [[foo|SandBox]]
