If you have previously recommended this thread, you should see a tick / check mark on the recommend button.

If you added a comment with your recommendation, you will need to delete that from your facebook wall separately.
Please could someone point me towards the idiot's guide to MN: I can't read profiles; I can't find threads I've posted on (can one tell if they have been deleted?); I can't find out if the thread I'm looking at is a duplicate of one by the same person from the previous week. I know that some people allude to poster's previous threads so there must be a way to find them but I don't seem to be able to work any of this out for myself! Thanks in advance.
