-<p align="center"><b>Help on writing Wiki Formatted Pages</b></p>
-
-<p>
- Wiki formatted pages provide a facility for marking up plain text with intutive human readable
- conventions that will be converted to XHTML when displayed. The big advantages are that you
- do not need to learn HTML to produce quite complex results, and that the text you write
- <em>looks</em> right to the eye even before conversion.
-</p>
-
-<p>You should enter basically plain text. There are a number of <em>special</em> characters you
-can add to insert formatting</p>
-
-<h3>Block level formatting</h3>
-
-<p>
- Paragraph blocks are separated by at least one blank line. To add special formatting to a paragraph
- add one of the following special characters in the first character of the first line of the block followed
- by a space...
-</p>
-
-<table>
- <tr><th>Character</th><th>Block Type</th></tr>
- <tr><td>No character</td><td>Ordinary paragraph</td></tr>
- <tr><td>></td><td>Quotation</td></tr>
- <tr><td>Space</td><td>Preformatted Text (Monospaced)</td></tr>
- <tr><td>%</td><td>Preformatted <em>and</em> Wikki formatting is ignored</td></tr>
- <tr><td>!#</td><td>Heading - where # is 1-6, the heading level (1 is biggest)</td></tr>
-</table>
-
-<h3>List formatting</h3>
-
-<p>simple lists can be constructed easily by placing a special character at the start of each line in the list followed by a space.
-The list is terminated by a blank line. At present lists cannot be intermixed or nested. Definition list
-definitions and text types maybe freely intermixed to obtain the desired effect however. The special characters
-are as follows...</p>
-
-<table>
- <tr><th>Character</th><th>List itme type</th></tr>
- <tr><td>*</td><td>Unordered List (bullet points)</td></tr>
- <tr><td>#</td><td>Ordered List (1,2,3 etc)</td></tr>
- <tr><td>:</td><td>Definition list, definition</td></tr>
- <tr><td>;</td><td>Definition list, text</td></tr>
-</table>
-
-<h3>Inline formatting</h3>
-
-<p>Inline formmating allows part of a line to be marked as having a particular style. The special
-characters used can appear anywhere on a line, but note that the formatting cannot
-cross lines. Codes are as follows...</p>
-
-<table>
- <tr><th>Example</th><th>Example</th><th>Formatting</th></tr>
- <tr><td>*hello world*</td><td><strong>hello world</strong></td><td>Strong or Bold</td></tr>
- <tr><td>/hello world/</td><td><em>hello world</em></td><td>Emphasis or Italics</td></tr>
- <tr><td>+hello world+</td><td><ins>hello world</ins></td><td>Inserted text</td></tr>
- <tr><td>-hello world-</td><td><del>hello world</del></td><td>Deleted or Strikethrough</td></tr>
- <tr><td>hello ~world~</td><td>hello <sub>world</sub></td><td>Subscript</td></tr>
- <tr><td>hello ^world^</td><td>hello <sup>world</sup></td><td>Superscript</td></tr>
- <tr><td>"hello world"</td><td><q>hello world</q></td><td>Quoted</td></tr>
- <tr><td>%hello world%</td><td><code>hello world</code></td><td>Code or Monospaced</td></tr>
- <tr><td>@hello world@</td><td><cite>hello world</cite></td><td>Cite</td></tr>
-</table>
-
-<h3>Acronyms</h3>
-
-<p>Acronym tagging is acheived by placing the acronym in capital letters followed by the description
-is parenthesis. There must be no space between the acronym and the parenthesis. Example...</p>
-
-<p>HTML(Hypertext Markup Language) <br /> <acronym title="Hypertext Markup Language">HTML</acronym></p>
-
-<h3>Automatic reformattion</h3>
-
-<p>Many commonly used functions are converted into their XHTML equivalents automatically.. The main ones are as
-follows...</p>
-
-<ul>
- <li>HTTP links are converted into active links
- <li> ..., (R), (TM), (C), 1/4, 1/2, 3/4 are all converted to the correct character
- <li> digits x digits converts to correct multiply symbol
- <li>A line starting with at least four dashes is converted into a horizontal line

+ Wiki formatted pages provide a facility for marking up plain text with intuitive, human readable\r
+ formatting that will be converted to XHTML when displayed. The big advantages are that you \r
+ do not need to learn HTML to produce quite complex results, and that the text you write\r
+ <em>looks</em> good to the eye even <em>before</em> conversion. It is a real alternative to \r
+ saving Word files as HTML retaining the ability to edit the resource online.\r
+</p>\r
+\r
+<p>You should enter basically plain text. There are a number of <em>special</em> characters you\r
+can add to insert formatting</p>\r
+\r
+<h3>Block level formatting</h3>\r

+\r
+<h3>Moodle Module Links</h3>\r
+\r
+<p>If you know the Moodle id number (look for ?id=nn at the end of a module address) and \r
+the module name, you can link directly to that resource using the syntax:</p>\r
+\r
+<p>ModuleName:nn(Description Text)</p>\r
+<p>eg, <em>resource:36(My New Page)</em> <em>forum:10(Jump to forum)</em></p>\r
+\r
