This site is dedicated to helping people who have strong body odors, but are not necessarily aware of it, or of the impact it has on the people around them.
I have a strong body odor and I want to do something about it.
Firstly, generate a PDF file of boinfo.org "business" cards. Once you have it, download it and either print it yourself, on as stiff paper as you can, or take it to a print shop to get it printed.
Once you have them printed, cut them out and keep some in your pocket. Any time you encounter someone who needs to tend to their body odor, you slip a card in their pocket or bag. Always wait at least at week before doing it again to a person to give them a chance to change, but also so that if they find multiple cards in their pockets/bags, it's from multiple people.
If you work in an office, or have a hobby in a community and encounter people with body odor issues, print a stack to leave out around the office, or where you gather as a community.
Pick from a popular phrase, or enter your own wording.
This is a rough idea of what it will look like
