I was just noticing that the Wikipedia page needs a bit of work. Or a lot of work.
Here is a link: http://en.wikipedia.org/wiki/Menstrual_cup
And here is a link to statements that are in regard to several issues with the page, including poor wording and lack of sources: http://en.wikipedia.org/wiki/Talk:Menstrual_cup
If there's anyone here who is a contributor for wikipedia, thinking about becoming one or even just has some links to articles others can use to reference the page that'd be wonderful. I know a lot of people go to wikipedia to find info on various things these days and we could make it a much better page :).
Don't feel obliged, I know it's not our job to regulate all cup related things on the interwebs >< I just think some of us could be interested in doing so :). I know I plan to.
