Yeah, I've definitely been on neopets and this site at the same time. I really hope they can't tell that from cookies. Seems like a major invasion of privacy.
Thanks! I wanted to try that for a while so I'd get comfortable with the program but I haven't done much looking for good proxies. I know that they're not always reliable so I was just going to create an account using another computer and internet connection and only play that account there. But proxies would definitely be more convenient. haha
