Drupal 8.x

Is it possible to create nodes by emailing the content? I am trying to help a very non-techy person with his site, and if he can simply send email that would be more his speed. This is for a D8 site.

Thanks.

I am using group module to set up a membership site which will access by different departments. The site works as expected that each department only can post/view own articles. but the  search cannot be integrated with group but returns  all related nodes were created by  all groups.  May anyone expertise help an idea?  very appreciated!  Thanks!  

The checkbox elements have the option to limit to available checks, but I need the possibility of a minimum number of checked boxes. So if there are four boxes to check, than should, for example, at least two be clicked. Ist this possible in any way?

In the activity report, I have the report of these errors
S.S. Mistakes  https://ibb.co/TT0NBcq
Not knowing how to solve the problem, I deleted the fields from the various Content types. Having recreated the fields, the problem has arisen again. How can I do to fix the problem permanently?

So I've searched far and wide and I'm pretty sure I thought this was possible to do.

I looked in the comments of entity.api.php

it says

 *   ... ... ...for an example. You will
 *   also need to add a corresponding route to your module's routing.yml file;
 *   see the entity.node.canonical route in node.routing.yml for an example,

However i could not locate such an occurrence node.routing .yml. (correct me if I am wrong)

Please let me know where is this route defined.

Thanks
