Once you’ve paid, you set up the add-on in MakerManager. I usually get to that by going to our main website (dallasmakerspace.org) and clicking the Member Portal button up (way up – no, further up) in the right corner. From that drop-down (and it’s a hamburger if you’re on your phone), I click MakerManager. You sign in to your DMS account. If I remember right, you click the My Badges (on the turquoise bar), and you have the option there to set up your add-ons. Once you’ve set them up, you can add a badge, provided that he’s signed a waiver using the same email that you’ve registered him with.
If you’ve already done all that, then we should probably tag Infrastructure… but I’m not going to do that unless you’ve done the above, and he’s still not set up. And – you have a different email address, yes? Every person should have a unique email address for the system to work right.
