By April 1999, almost 100 organizations had been identified by the Virtual Volunteering Project as involving online volunteers and were listed on the web site.[17] Due to the growing numbers of nonprofit organizations, schools, government programs and other not-for-profit entities involving online volunteers, the Virtual Volunteering Project stopped listing every such organization involving online volunteers on its web site in 2000, and focused its efforts on promoting the practice, profiling organizations with large or unique online volunteering programs, and creating guidelines for the involvement of online volunteers. Until January 2001, the Virtual Volunteering Project listed all telementoring and teletutoring programs in the USA (programs where online volunteers mentor or tutor others, through a nonprofit organization or school).
