toread is an interesting bookmarking service working by email. Registration is very simple:

• Registration form requires only your email address
• A confirmation email is sent with a link to activate the account
• On the activation page, there is a link to install a bookmarklet

Once the bookmarklet is installed, you just have to trigger it to automatically send to your mail account a copy of the page that you are browsing.
What is amazing about toread, is that it is faster than a file save.
Other bookmarking services like furl, offer the ability to bookmark page and save them at the same time. But I found toread  more convenient.
