Thnks, Nigel, I didnt realise that was an option. But it's a pity there's no little thing to click on explaining that at the top of the list. How is someone coming into Mudcat expected to find that out? Maybe I'm missing something, but what would be wrong with Mudcat as it was, but with a button to click on if you want to separate the threads into two groups? I appreciate I may be going over old ground, but I've been away, and I can't help thinking that what I am saying is blindingly obvious. What am I missing?
