Thank you for the suggestion! Unlicense does seem much better and their website has a valid SSL cert, unlike the wtfpl one... So, this is probably the one!
Will update the repo later tonight! Cheers!
By choosing a rebel license like the WTFPL or Unlicense, you are going to limit your world of potential users and collaborators. There are people that do that deliberately, such as Doug Crockford and the JSON license, but if you're going to do that, you really should do it from a position of expertise.
To maximize the reach of your program, you would be well-served to select one of top-ten or top-twenty popular FOSS licenses. I could provide a list but any list would be biased; just google it.
I have my opinions about which FOSS license I would select, but I'm going to suppress them because I just want to help you ease into the mainstream.
A decent way to choose would be to look at what community you want to be a part of and see what the predominant license choice is within that community.
