Codepaste

Codepaste allows visitors to share their code, without losing its format.  You can paste files, or upload them.  Some of its features include ownership, revisions, and branching.  And all this, without ever having to sign up or sign in. (In fact, there is intentionally no way to sign in.)

Any code you add, be it by pasting, uploading or branching is owned by you. You can edit it, and save new revisions. Every file has a public key: a string of characters you can give to your friends, or anyone you want to be able to revise your files – ideal for situations where you’ve grown too accustomed to some code, and need fresh eyes to spot and correct an error.

Codepaste will email a link to the code to a friend, or you can download the code for use.
