This site has always tried to help, inform, and entertain people, and I've tried to keep it as ad-free as possible, which is a rarity for a Web site.
It costs hundreds of dollars a year to host this site and it requires hundreds of hours to maintain and update it.
Nice2know.com is currently funded, designed and maintained solely by the owner and it will only survive through hard-work and the support and input of members like you. If you appreciate what I've done, and/or wish to keep the site going, please help me in any way you can.
