ureka now supports OExchange - so the url sharing 'linker-button' has changed

OExchange is a protocol that allows social sites to share links easily and now ureka.org supports this helpful feature. you can now add links to your list of external links by using URLs with the format:
https://www.ureka.org/oexchange/share?url=http://www.websitetoshare.org

usually though, you won't be typing the address manually, since you can use the linker-button and soon ureka will be available from sharing tools such as those available from addthis.com and sharethis.com (subject to being accepted by their team for inclusion). if you already use the linker-button you will need to grab the new version and remove the old version from your browser's toolbar.
