If Public was open , close it for now and open the Digital and Radio ID list. You will see the info in the above image. Enter your radio ID and your callsign. Of course your ID won't be 12345678. You need this ID and if you do not have one you can get one at this site. https://www.radioid.net/account/#!
click signup and fill out your info and make an account. In a few days you will receive an email with your ID. Save this email for future reference.
After that go to https://brandmeister.network/?page=register with your new ID# and fill the form out and you should get an email in a few days.
This was the most confusing part for me but once I did it, what a breeze. That ID# will be used in other area like hot spots and other programs so keep that number for all future reference. Like a SSI number it is unique to you.
Once ou have your ID move on to section 2 TALK Groups.
