[quote=@Cannon011]
I'm new. Help me. I tried to reply to a post, but I can't figure out how. When I tapped the button labeled reply, it didn't say which post I was replying to. Please help me out. Thanks.

If you use quote, it tells you who you're quoting. Alternatively you can use @mention, which does this: [@Cannon011]. You can find both at the bottom right of the post you want to reply to.
