I tried to link my MH and FB accounts today. MH seems to have linked them (one password allows access to both) but FB claims I have no linked accounts. No menu came up asking if/what I wanted MH to post to my FB account and no MH posts have appeared on my FB feed. How do I: 1) know if they are linked and 2) unlink the accounts---I didn't see any benefit, after linking, that justifies worrying about privacy & security. Thank you.
