“Almost all sites have a feedback system.
But as a rule, it is inconvenient, or completely absent.
Each Administrator wants to make his site the most convenient, interesting and informative.
Very often situations arise when site visitors need to contact the administrator, but due to the nuances of the feedback system, the Administrator receives this message in a week, or does not receive it at all.
It can be a message about cooperation, a question, or just important information about problems on the pages of the site.
