What's the best plugin/software to do this?



Someone contacted me for something, he wants me to help him with it.

He wants to grow his youtube channel, so he came up with an awesome idea.

He is to run a giveaway, so to contest for the giveaway, you will have to subscribe to the youtube channel, your name and your email (he will send stuffs about the giveaway, etc toothe email someone submitted). Then you will start to refer more people, the person with the highest refers will get the giveaway.

So what’s the best plugin (if I am to use WordPress) or what’s the best software for this? I think WordPress will be more good, I can handle this perfectly.
