Those are fine too, although Google gives you better results. It's a pain to use over Tor, but that's life. My point is that nobody here knows the URL for Torchat off the top of their head, and it's an easy question to answer. If OP had Googled it, he'd have the answer, but instead he expects us to do it. People need to stop being so helpless and start doing their own research, especially for simple questions like this. If you want to know whether your ISP can fingerprint the hidden services you are visiting, that's a question for this forum, since the answer isn't readily available in a simple search engine query. But stuff like this is wasting our time.
