I am using the flexinode module an created a content type with a table. Where can I adjust the layout of the table, columns rows?

Is there a module / feature in drupal that sends an automatic email to all registered members of recent postings?

Like, if a member posted a new article / forum topic in my website, all members will receive a newsletter in their personal email addresses (but only if they ticked the checkbox for news update)? Could members select weekly or monthly updates?

Right now, I do this manually & it's taking up most of my time.
