reCAPTCHA and popup tweaks

Linkatopia has just added a new tool called reCAPTCHA to the signup form in order to prevent automated account creation. reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher.

Toolbar Popup Tweak
We've made some improvements to our popular browser toolbar button that makes it easy to save links. If you have more than 40 tags, only the most popular ones will be shown first, allowing quick access to the tags you use most often. Simply click "more" and you'll see all of your tags. Your Linkatopia page still displays all of your tags.
