Just a bit of information to all the pastebin.ca users.
At the request of users, we have added a feature so you can mark
your posts for automatic deletion when you create them. If you
don't mark them at creation time, you will have to use the normal
ways of having a post removed.

If you mark it for expiration, it will display on the page until
the expiry time. It will then be automatically deleted from the system.
It will also mark the page as non-indexable by search engines, so
cached pages shouldn't show up in them.

If you do not pick a time, the default behavior is to keep the paste
forever, unless you request from us to have it removed. Pages not marked
for expiry will also be indexed and cached by search engines like Google.

Thanks for using the Pastebin.
