The Le Meow forum, just log in or sign up, don’t worry about any extra steps. Also that forum is way easier to use than this old thing here so should hopefully be no issues!
Always all good with questions. I don’t know about Websites to buy uncut lenses. Depends very much on what country you’re in. I used to just buy them on ebay or depending where I’m at, local wholesalers (in big cities in Asia that’s also easy).
