This is a small professional network of colleagues.
I recommend them to you. Here's how we got our name.
When I would have a problem with my work, I'd ask a colleague to help me. They would come and stand on the magic square of carpet by my desk. Sometimes just their presence seemed to fix the problem. Other times their expertise helped me. We have stood on each other's magic squares many times, and we promised that we'd continue to help one another, even after we no longer sat in the same row of cubicles.
