Make sure you are already logged on to The Grint website then ->  ***CLICK HERE***
You should see something that looks like the screenshot below.  You need to become friends with everyone on the JBG Tour .  One name at a time, type the names of fellow JBG Tour members into the "Find Friends" box outlined in red below and click on “Go”....

 
Once you have finished your account registration on the Grint, please send Grint friend requests to me and to Kevin Curtin from The Grint app or The Grint website, starting with me, to ALL members of the JBG Tour.  Please open the PDF document attached to this email for the step-by-step instructions on how to do this.  Again this should only take a couple of minutes of your time.
