Teaser Preview Text

Anyone have any ideas on how to add teaser text of the post prior to the user signing up?
A bit like https://rediverge.com/necker-island/


Not possible yet, although it is apparently coming. Meanwhile, John mentions how he pulled it off on Rediverge here:

I guess you can’t use the {{excerpt}} helper with article content? There’s also the excerpt field on the Post itself. Otherwise, you could perhaps repurpose a metadata field as teaser text?

I saw theme vendors using the {{excerpt}} to do what you what. I personally don’t like this behavior.
