Created by one mind of one person.
Start with helping one.
Goal to live as one; irrespective of caste, religion, status, wealth, sex, ethnicity, culture.

'One' seemed to be a common theme that was constantly hitting me in the face as I was creating the beginnings of this 'project' and trying to settle on a name.

Other choices were: 'Just for One', 'The Little Things', 'One? International', or 'All for One'.

I decided on One! because it was simple and positive, in that one word and that one bit of punctuation, SO much is implied!
