The official LinkLocker Chrome Extension is now available on the Chrome Web Store. Browser extensions will be the best way to add content to your LinkLocker account going forward; they are more secure than the bookmarklet in a number of ways, they can be easily updated, etc. All of our current beta testers who use Chrome are encouraged to install the extension right away.
If you're using Firefox or Safari don't feel left out; extensions for those other platforms will be coming very soon.
