The difference between Read Only and View Only permission

Today I came across a very good debate on View Only and Read Only permissions during a lunch break (in fact we all had a great FUN J)

Briefly speaking, View Only is one of the default permissions that can be directly assigned to groups or users in SharePoint sites; Read Only is a mode of viewing document.

They have some relations in SharePoint. View Only permission gives users the right to view pages, list items, and documents, but prevent any modification. That means, in item level, document can only be viewed in Read Only mode by the users with View Only permission.

Unable to add DL to sharepoint permissions

Issue
 whenever you try to add a DL to sharepoint permissions, it doesn't resolve and gives an error

Resolution
 If you want to add any DL to the sharepoint permissions, it should be converted to Security Groups. As soon as that is converted to Security Group it will be resolved in the permissions section and users will be able to access the site.

Note: If those DL's are having SUB DL's inside it , then they should also be converted to Security Groups.
