Just like SandyG mentioned P2PU is a community that I will always use as a tool in the future. Even though I've never met anyone in this community I've learned so much from everybody. Everybody has come here with some fantastic ideas and great information for us to use. It's cool to communicate with people with the same dreams as me. I love how we can share our opinions, struggles, and findings with each other without feeling like we're being judged. I like how we created a safe enviornment to learn in. I can tell that everyone will do great things as teachers.
I don't know of any other tool that I can use because I haven't been a part of any other community. But I will surely explore more places to expand my resources. This picture I found on the link made me realize that I use a lot of other search engines that can be useful for teaching and as my PLN. I usually use them for leisure and other stuff. I never thought of taking advantage of them for teaching and learning. Now I have plenty of tools to use.
