I am slowly trying to get to grips with Twitter, having finally and belatedly discovered it can be a useful tool for communicating. At the bottom of a MHF page is a button to share the page on Twitter. I tried this on a thread I started and was able to re-tweet it but the tweet only showed thumbnail pictures and when I clicked on them I was told I needed to be logged in. Is this as it should be? MHF will come across as unfriendly if it is!
