I am sure there is someone here that can explain it better, but i will tr:
Here goes:
When you log into your account, you will see your creations. There is a option to post (or post again) your creation. Click on one of those. A new screen will pop up showing facebook options...ignore those....up at the top left, there are symbols...click the word more...another screen pops up for your to "blog your creation". On this screen there is an option "Just need the link" ..... copy this link and then paste it into your thread. (if you don't know how to copy it ..... highlight it, right mouse click and choose copy ..... then go to your thread .... right mouse click to paste it) This should work! Good luck!
