I had the idea for Jekalo.com three years ago, but @Motoni_Bolarinwa stole my idea! It doesn’t matter that we’ve never physically met or knew of each other till a week or so ago. 
Gonna take the “no one is going to steal your idea” concept a bit farther and ask – your idea? Yours? No, it’s not YOUR idea. Nobody owns ideas (unless maybe you are Elon Musk, lol). They float around in the common ether till someone pulls them out and does something with them.
