Hello all! First time poster... long time listener to the program...

I have been tasked with leading a group of employees and board members on their quest to create a new vision statement for our credit union.

We have landed on a nice little stream of words, but I am having difficulty with the grammar. I am sure this is something I should have learned in fourth or fifth grade, but I can't seem to remember.

The statement we have is: "We create lifelong relationships that capture our members' imaginations."

I am ok on the plural of "member" because we have more than one member. Since it is that group's imagination it needs to be possessive. Where I am having trouble is whether imagination should be plural. Each member only has one imagination, but the group has many. By making imagination plural are we saying that our members share their imaginations with each other? Maybe I am just over thinking this.

Any help would be greatly appreciated!
Mike
