Repository license?

[joshbarrass]

Currently this repository is unlicensed. From GitHub's own licensing docs:

You're under no obligation to choose a license. However, without a license, the default copyright laws apply, meaning that you retain all rights to your source code and no one may reproduce, distribute, or create derivative works from your work. If you're creating an open source project, we strongly encourage you to include an open source license.

which, as far as I understand, forbids any kind of open source contributions from the community (such as pull requests), as copyright laws forbid others from creating derivative works.

I just wanted to know whether this is an intentional decision, to keep the contents of this repo strictly under copyright, or whether you'd be open to including an open source license?
