Something REALLY simple ?

 Hi,I think the problem is a result of comments having a reply link at the bottom of each comment while the main post does't have it. Th e fact is that if you just scroll to the end of the page and post a comment (without hitting the reply button) that counts as a reply to the main posting.We are going to implement a few more changes (hopefully by the end of August) - nothing drastic just taking care of issues like that and I hope that will make things clearer.

I had the same prob as Sprostoni because I didn't realise the "Post" button was actually marked "Save" (and it's right at the bottom of the page)And Ronald, the reply system does make a thread v disjointed.  I understand that people want to indicate what post they are replying to - but I think a quotes sytem worked better and didn't interrupt the flow
