Hello,
I am confused as to how S5 Box classes works:
1. I don't know where to publish the actual s5 box to a non s5 box position. Where is the actual s5 box in the admin section?
S5 Box is automatically active when you activate the plugin, there is no special widget you have to publish; the Joomla version had that limitation, but I made it so the WP version wouldn't.
2. LOGIN...
Do I simply publish a text widget withe the following HTML to LOGIN widget position?
<a class="s5box_one">LOGIN< /a>
The login position is already an S5 Box position. All you have to do is publish whatever you want to that position, and when someone clicks the "Login" button on the site, whatever widget(s) you have published to that position will appear.
