I googled 'menstrual cup community' to see if there were any forums created so far and came upon this site: www.lovemycup.com
The site itself looks pretty good (nice and neat) and has quite a lot of information. I particularly liked their comparison chart and the thing that caught my attention was their store. They claim that they are a one-stop shop for menstrual cups and they are almost there. They seem to have almost all the cups listed on their site:
I wasn't sure if this site was brand new or old so I did a whois.com search on it, and it looks like its registered in the States in 2008 but is expiring May 2009. I find it odd that it carries both the MoonCup US and the UK while it is located in the states. I sent an email through the contact form asking when their store is opening up (since everything says coming soon) and whether they ship worldwide and hopefully they'll reply.
Has anyone else heard of them or have experience working with them? I searched through the 'where to buy' tag up to the middle of 2008 and didn't see anything on them (although I might have missed it if it is in a comment since I can never get that search to work!)
Btw, the site even has this site listed under their 'How to Use' page.
ETA: I found their Carts page and it said this which answers their location and where they ship question (sort of)
"Shipping: Please allow 5 business days for delivery to the continental United States. Shipments to Alaska and Hawaii may require more time. Buyers outside of the US should contact Love My Cup before completing the purchase. "
But they still don't have stock for you to actually purchase. On the homepage it also says "Free Shipping with purchase of 2 or more cups" so that's a very attractive option...
