If you’re having trouble sharing, it is most likely an issue specific to your browser settings and the service (Facebook, Twitter, Tumblr, etc.) you are attempting to share through.
If you're using a phone, make sure to share from a browser (not within an app) and/or try a desktop/laptop
Try a different browser (the latest version of Chrome is often most successful)
Make sure an ad-blocker is not preventing the sharing feature from properly operating
Try logging out and back into Tunespeak and Facebook
Remember that links do not expire. You may re-share or re-tweet your earlier links. If you're unable to share to a friends' wall, try sharing to your own wall, and tag friends.
If these options do not work, please email us, and indicate whether you were able to share previously in the contest.
