 <p>Blocks are the boxes visible in the sidebar(s) of your web site. These are usually generated automatically by modules (e.g. recent forum topics), but you can also create your own blocks.</p>
-<p>The sidebar each block appears in depends on both which theme you're using (some are left-only, some right, some both), and on the settings in block management.</p><p>Whether a block is visible in the first place depends on four things:</p><ul><li>It must have its \"enabled\" box checked in block management.</li><li>If it has its \"custom\" box checked in block management, the user must have chosen to display it in their user preferences.</li><li>If the \"path\" field in block management is set, the visitor must be on a page that matches the path specification (more on this later).</li><li>If the block has its throttle box checked, the user will only see the block if the site throttle level is low.</li></ul>
-<p>The block management screen also lets you specify the vertical sort-order of the blocks within a sidebar. You do this by assigning a <strong>weight</strong> to each block. Lighter blocks (smaller weight) \"float up\" towards the top of the sidebar. Heavier ones \"sink down\" towards the bottom of it.</p>
-<p>The path setting lets you define the pages on which a specific block is visible. If you leave the path blank it will appear on all pages. The path uses a regular expression syntax so remember to escape special characters! The path expression is matched against the relative URL of a Drupal page, e.g. <code>book</code>, <code>node/12</code>, <code>admin</code>.</p>
-<p>In case you do not know what a regular expression is, you should read about them in the PHP manual. The chapter to look at is the one on <a href=\"%pcre\">Perl-Compatible Regular Expressions (PCRE)</a>.</p>
-<p>However, for basic tasks it is sufficient to look at the following examples:</p>
-<p>If the block should only show up on blog pages, use &lt;^blog&gt;.  To display on all node views use &lt;^node&gt;.  The angular brackets are used as delimiters of the regular expression.  To show up on either forum or book pages use &lt;^(forum|book)&gt;.  The round brackets form a group of expressions, divided by the | character. It matches if any of the expressions in it match.  A more complicated example is &lt;^node/add/(story|blog|image)&gt;. Blocks which have their paths set to this expression will show up on story, block, or image composition pages.  If you want to show a block an all pages, but not the search page, use &lt;^(?!search)&gt;.</p>

+<li>Its path options. Blocks can be configured to only show/hide on certain pages</li>.

 <p>Blocks are the boxes visible in the sidebar(s) of your web site. These are usually generated automatically by modules (e.g. recent forum topics), but you can also create your own blocks.</p>
-<p>The sidebar each block appears in depends on both which theme you're using (some are left-only, some right, some both), and on the settings in block management.</p><p>Whether a block is visible in the first place depends on four things:</p><ul><li>It must have its \"enabled\" box checked in block management.</li><li>If it has its \"custom\" box checked in block management, the user must have chosen to display it in their user preferences.</li><li>If the \"path\" field in block management is set, the visitor must be on a page that matches the path specification (more on this later).</li><li>If the block has its throttle box checked, the user will only see the block if the site throttle level is low.</li></ul>
-<p>The block management screen also lets you specify the vertical sort-order of the blocks within a sidebar. You do this by assigning a <strong>weight</strong> to each block. Lighter blocks (smaller weight) \"float up\" towards the top of the sidebar. Heavier ones \"sink down\" towards the bottom of it.</p>
-<p>The path setting lets you define the pages on which a specific block is visible. If you leave the path blank it will appear on all pages. The path uses a regular expression syntax so remember to escape special characters! The path expression is matched against the relative URL of a Drupal page, e.g. <code>book</code>, <code>node/12</code>, <code>admin</code>.</p>
-<p>In case you do not know what a regular expression is, you should read about them in the PHP manual. The chapter to look at is the one on <a href=\"%pcre\">Perl-Compatible Regular Expressions (PCRE)</a>.</p>
-<p>However, for basic tasks it is sufficient to look at the following examples:</p>
-<p>If the block should only show up on blog pages, use &lt;^blog&gt;.  To display on all node views use &lt;^node&gt;.  The angular brackets are used as delimiters of the regular expression.  To show up on either forum or book pages use &lt;^(forum|book)&gt;.  The round brackets form a group of expressions, divided by the | character. It matches if any of the expressions in it match.  A more complicated example is &lt;^node/add/(story|blog|image)&gt;. Blocks which have their paths set to this expression will show up on story, block, or image composition pages.  If you want to show a block an all pages, but not the search page, use &lt;^(?!search)&gt;.</p>
