-        This node usage is at @Model.Saturation%<br/>

-    <h2>FAQ</h2>
-    <h4>Why is there a limit on the node?</h4>
-
-    <p>BirdsiteLIVE rely on the Twitter API to provide high quality content. This API has limitations and therefore limits node capacity.</p>
-
-    <h4>What happen when the node is saturated?</h4>
-
-    <p>
-        When the saturation rate goes above 100% the node will no longer update all accounts every 15 minutes and instead will reduce the pooling rate to stay under the API limits, the more saturated a node is the less efficient it will be.<br />
-        The software doesn't scale, and it's by design.
-    </p>
-
-    <h4>How can I reduce the node's saturation?</h4>
-
-    <p>If you're not on your own node, be reasonable and don't follow too much accounts. And if you can, host your own node. BirdsiteLIVE doesn't require a lot of resources to work and therefore is really cheap to self-host.</p>
