Hello write2mon,

I can see the importance of having the option to add donors to other customer's projects.

With that, I recommend sharing this suggestion with our developer's team. Here's how:

1. Click the Gear icon, then select Feedback.
2. Type in a few words as a description of your feature suggestion.
3. Click Next.

Furthermore, you can check this article as your guide in managing projects: Create and manage projects.

I'm always around if you have other concerns with creating projects.
