Custom Capabilities section

I have read almost all the custom capabilities posts so far but I dint get the answer of one silly question

Optional. This is VERY advanced.
See: s2Member -› API Scripting -› Custom Capabilities.

*ADVANCED TIP: You can specifiy a list of Custom Capabilities that will be (Added) with this purchase. Or, you could tell s2Member to (Remove All) Custom Capabilities that may or may not already exist for a particular Member, and (Add) only the new ones that you specify. To do this, just start your list of Custom Capabilities with `-all`.

So instead of just (Adding) Custom Capabilities:
music,videos,archives,gifts

You could (Remove All) that may already exist, and then (Add) new ones:
-all,calendar,forums,tools

Or to just (Remove All) and (Add) nothing:
-all

How to add those sections in wordpress? Is that category (gifts, calendar etc)?
What if I want to add certain pages to a membership level and other pages for another membership level?
What if I want to create level 2 but I dont want it to see the level 1 stuff?

Ok here is the full scene:

I have a website with membership level 1 but now I want to add another thing in same website and monetize it. But I want both of those things separate from each other. The person will see dedicated stuff on login. Is this possible?

Also, is it possible to have different welcome pages?

Custom capabilities are not categories. This video will help understand them better: Video » s2Member (Custom Capabilities)

Also, is it possible to have different welcome pages?

In the page you chose for the Login Welcome, you can use conditionals to show different things based on the level/access. [hilite path]Dashboard -› s2Member® -› API / Scripting -› Simple/Shortcode Conditionals[/hilite]
