Since Vipassana, New Kadampa, and Diamond Way have been discussed, I'll tell you what I know of True Buddha School, Share, and FWBO.
True Buddha School was founded by Lu Sheng Yen, who was known as his disciples as the Living Buddha. It is rooted in the Vajrayana, or Diamond Vehicle, of Buddhism, who's most well known school is Tibetan. Like New Kadampa, and some other smaller sects, it is more akin to a NRM (new religious movement), that incorporates other religious teachings, such as Taoism, into it's belief and practice. To the best of my knowledge, it is a controversial movement, and has been given, what can basically be described as, cult status.
Share International is a movement founded by Benjamin Creme, who declared that the various messiahs and such has come, in a man he calls Maitreya, after the next Buddha in this current cycle. According to Creme, this person is also the second coming of Christ, al-Madhi, Kalki, the Jewish messiah, and other such personages. It has also been given cult status.
FWBO, now known as Tiratana, was a movement aimed at modernizing and westernizing Buddhism, to make it more appealing and acceptable to a western audience. Like these others, it is not considered an "orthodox" form of Buddhism.
