This platform has been good since I joined and has been all about giving especially by contest. 
I have invited like 4-5 people since I joined and today makes it the sixth day, I think I have tried, imagine if I have been here for long and my reputation has grown to 43. I have 2 screen shot to prove this I sent link that have joined through me while others, I just opened it for them or just talk to them on calls.
I hope to emerge the winner.
