First I have a request about other thing: I would like to receive Nostr Dm when any of my contributors create a new long post. So I can be reminded that I should add their article on my blog. Maybe a notification option on search settings here:

Nostr DM or even email notification.

Hmm... Could you use Habla to discover new post of your contributors? And then we could add automations like "if you post THIS emoji as reaction to a post - add it to the site". This way you'd be able to submit to the site from any client.

Hum, complicated, no? Haha.

OTOH we could do something like "saved searches" on our side, and then add notifications if new stuff was found for a saved search...

I would prefer receive Email or DM about new long posts of my contributors.

Yes.

Depends on your setup. If you are following all of your contributors and discovering their content in your daily-driver app (i.e. Primal has Reads now) then just posting a specific emoji or a specific zap amount is much simpler than going to our UI.
