Real names instead of nicks

I propose to consider the possibility of publishing the real name when viewing messages and comments, that is, instead of a nickname with a link to the profile, the real name will be displayed with a link to the profile.
This is especially convenient when someone replies to a comment and wants to contact him by name.

In “Settings >> Tuning” we make the option “Substitute my nickname with a real name” and everyone who wants to publish a real name will put a tick.
Those. This option will allow habrachelovek to make available its real name instead of a nickname on the pages of posts in blogs and comments.

Update: Voting on this issue
