Excellent thanks chaps.
I've just pulled down the latest code base and all seems to be working again.
I have a strange bug
Users who have more than 3000 (maybe the line 1000, but I didn't ask so many users, and users have been imported from our old forum to NodeBB) are seeing their post count updated wrong sometimes right after posting a comment to a topic.
The wrong number is only shown right after the post and is corrected on any reload.
I asked a couple of long time users, and it seems that the post number is their current post number / 1000 +1. And when testing one thread, it seems to grow by one if the user doesn't reload in between.
It's not a real problem, more of a strange/funny bug.
We run 0.6.x in a cluster setup (redis+mongo), if that has any impact.
