I recently started a page on Menstrual cups: http://www.appropedia.org/Menstrual_cups . Appropedia is a sustainable living wiki, so I thought it was perfect. Yay for spreading the word. 4+ years and I'm still going strong with mine. I love it. In fact I love that I don't even think about it any more, it just does its job without interfering.
Anyway I would appreciate any additions or corrections (you can edit the page yourself - without an account - or just leave a comment here and I will update it). And if someone wants to write a short article on cloth pads that would also be ace. :)
