Ogads LP or locker ?

Hi guys,
i have come across this forum, only a week ago, i must say i love it. I've read tons of things, and will now try to get into the OGADS business.
So, I am all setup with OGADS, but there is one thing that still confuses me (sorry it that's obvious) :

I have made LP requests and got approved. This has also generated some related content lockers.
What i don't understand is :

• do those LP actually unlock some content when the survey (or whatever) is completed ?
• If I use the locker in my own LP, should I then add some content of mine with the locker, or is it automatically using some preconfigured content OGADS has setup ?

Sounds like a naive question considering the forum name
Anyway, i need to make sure.

Cheers !

No, the lockers don't unlock anything unless you edit them to unlock something (a link, the page)

And do (we) usually use them as is ? With no content ?
