I have an account with a test site that I am the Owner of. I have purchased a bunch of add-ons. In my account it asks me to assign them to a project, and naturally just lists my test project in the drop down. However, I have hired a developer to build my site in C5, so I assume they have an account and my real site under development as their project. What is the best way to assign all those add-ons to their project?

I have read the instructions that offer:
Login as the owner of your Project page
Goto the Project page, and look for the Management Team section about half way down.
Add the other accounts in question to that list.
Login with your other account to concrete5.org
Now your second account should be able to see the project page and assign licenses which will be automatically available for install on your site through Add Functionality

Sorry but I am confused with this: Do I get my developer's account info and put it in my Management Team section? Wouldn't that put him under my test project instead of the real project? Or do I have him put me and my account in under his Management Team and then could assign add-ons from there?
Thanks for the help. John
