Oh, (and this is probably rather more serious from a development point of view) - it seems you've got a caching/update issue - I click on the bell at the top to get a list of updates, see that Talkative Toad has quoted me, click on that update, and it goes ...nowhere... because the page I'm on isn't updated with the new posts until I refresh.
(Or, where I first noticed this, see my post saying "This is awful" has 4 reps, go to it, and it says it only has 1 rep until I refresh).
How did your beta testing not find any of this? I mean, I've moaned about our testers not finding stuff, but this is another level entirely!
