For various coaches personal page
When it comes to coaching what comes to mind in most cases is sports. But coaches are not restricted to sports alone. We could also have coaches in other profession apart from sports. In fact anyone teaching another person how to do something better could easily be referred to as a coach really. So if this applies to you and you are trying to create an online presence for yourself or business, then the .COACH should be the domain name of choice for your business.

Most coaching jobs you will find online are usually sport related and new opportunity tends to open a lot in that field. So it would be a very great thing to have a job portal dedicated to coaching related jobs with a .COACH domain.
