To add a new panel to your website, click the 'Edit Theme' tab in your Admin Panel, then click 'Edit Panel Layouts' in the right menu.
At the bottom of the page you have several options, you can design your own panel using either BB code or in HTML (for advanced users), or you can add one of our panels which will add extra functionality to your website. For example, if I wanted to add a Twitter feed to my website, I would select Twitter in the list of panels. There are list of customized panels that you can also choose from.
To create a panel in either BB code or HTML, just enter in the title and the code at the bottom of the page. Once you've created a new panel for a specific page you may position it to wherever you like. You can also restrict panels to certain members, which is decided by rank.
Let me know how you get on.
