Temporary Inbox

I used to have a separate email address for those sites where you need to register before you could retrieve a document etc. Soon this kind of mailboxes become clogged up, that's essentially what they are for, right?

Well, I found a different solution: there is a site providing you with a temporary inbox just for this. You specify the temporary address, retrieve the email and forget about the mailbox right after that. And there even is a neat Firefox plugin that automates all this for you!

I found this service extremely helpful, so I am posting the link here. Hope some of you might find it useful too.
