The Women's Rugby Review blog has a couple of posts of interest to the high school girls rugby community generally. This blog has a link to a video and link to the website of the Letchworh Rugby club in England that produced a promotional video for girls rugby. This might be a useful video for clubs to use when introducing rugby to a new community.
Also, the Women's Rugby Review noted that USA Rugby has announced that it will sponsor, for the first time, a high school girls rugby championship, which is scheduled to be held on May 24-26, 2008.
