<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 are using (some are left-only, some right, some both), and on the settings in block management.</p>
<p>The block management screen lets you specify the vertical sort-order of the blocks within a sidebar. You do this by assigning a weight 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>A block\'s visibility depends on:</p>
<ul>
<li>Its enabled checkbox. Disabled blocks are never shown.</li>
<li>Its throttle checkbox. Throttled blocks are hidden during high server loads.</li>
<li>Its path options. Blocks can be configured to only show/hide on certain pages</li>.
<li>User settings. You can choose to let your users decide whether to show/hide certain blocks.</li>
<li>Its function. Dynamic blocks (such as those defined by modules) may be empty on certain pages and will not be shown.</li>
</ul>
