Over the years I’ve occasionally run into directories (for example, Yahoo!) that have a separate category permitting legitimate nonprofits to apply for a complimentary listing. I would appreciate knowing if there are any such directories owned by DP members with a nonprofit submission option. Thanks.
Yes, there is at least one Busybits offers free inclusion for non-commercial, quality sites. If you do submit, please send a PM with the URL in order to recognize your site in the pile of spam submitted in general to the directory.
