The only section that can scroll is your last custom section. So, instead of this:
This is my about information. Tada!
[list=1]This is a custom section. Ooo...magic!
[list=1]This is a second custom section. Wow!
[/list]
[/list]
Where you make #about scroll, you'd do this:
[list=1]This is my first custom section. (1st)
[list=1]This is my second custom section. (2nd, mmhm)
[list=1]This is the section where all my about info goes. (3rd custom section)
[/list]
[/list]
[/list]
Where #about doesn't scroll, but #about ol ol ol does.
You'd move the first two custom sections into place and then move the about section where you want it.
