Some people feel uncomfortable spreading the word about business and ideas in return for money.

If this describes you, there are 2 basic ways you can approach how you spread the word:

#1 You can join the affiliate program and when payments are made to you, you could donate these payments to charity in full - why not make this a marketing point in your own efforts, eg: "This is an affiliate link for JointWinWin.com, all affiliate commissions YOUR_BUSINESS_NAME_GOES_HERE receives will be donated to charity.

#2 You could spread the word without joining the affiliate program. Please refer to "What can I do to help" for more information
