I simply check out "new posts" each day and they come through all jumbled up together. I had to go on a search to find out which sub-forum you were talking about!
i.e. The "Where to Buy" sub-forum. Look at the list of links at the top which shows the sub-forum each thread is posted in. And if you're just riding the new posts link, then the forum is listed on the right hand column.
Maybe that's the confusion, forum = sub-forum in usage here. I use forum for the area such as "Property Investment Discussions" and the sub-forum as "Property Investment - Other" or "Where to Buy" or "Adding Value" etc.
