The Block Administration Page give you full control over the side blocks.
Title: The Title of your Block (you can use HTML in here)
Modify Blocks Screen:
The first links you see allow you to sort your blocks by Display All Blocks, Only Left Blocks, or Only Right Blocks.
The grid below this displays information on the blocks your site already has set
- Side: Which side of the website the block is displayed on.
- Order: The display order.
- Visible for: Who the block will be displayed for.
- Position: The blocks position (top to bottom)
- Visible: Whether the block is visible or not.
- Blocktype: What blocktype is set for this block.
- Action: Allows you to reconfigure or delete your blocks.
note: If you are new to MPN, your first step in here would be to turn the blocks you do not want invisible. That way they won't be displayed on your page, but you can always go back and see how they were configured.
