I receive letters from time to time, to join Adobe Partnership Program. Because Fotolia is closing and their PP is closing too.
But what is this APP? How to get there? I don't see any links or any mentions in FAQ.

It's on Russian, so I can't quote.
Switch to Adobe Stock Partnership program. Fotolia partnership will be closed on May, 6. You can earn by publishing links, banners or integrate API, etc. If you need more info, follow the link. And link is leading nowhere.

I think you are talking for affiliate with Adobe, if you have a site or blog to publish their ads.

Thanks, probably you are right.
But it looks complicated. I had simple referral link for buyers on Fotolia. But on Adobe I have to register a separate account with slightly broken interface. Meh...
