If you delegate you will get one upvote per day on your posts on autopilot.
If you don't post I will automatically switch to paying you out instead. No action is required from your side.

The part you refer to above is when you manually vote using @zero-profit. You can send me links to posts in the memo and I will upvote them with the sp you delegated. In order to make sure nobody abuses this I track an internal 'voting power' for all my delegators and when that gets too low you cannot upvote through me anymore until it has recharged. But this is a completely optional feature.
