Probably not doing something right but here is my dilemma. In using the old search feature it was possible to choose a forum to search in. That doesn't seem available now or am I just doing something wrong or not understanding how to do it? 
Winston.....if I understand your question....do the following....
Go to bottom of your first page.
Click on Quick Navigation (mine says Yanmar by default)
All the forums can be searched there.
Hope this helps.
I am in the Yanmar forum. I see a "search" at the top of the page but do not see a "search forum". Sorry I'm so dense. :ashamed:
I just found it: http://www.tractorbynet.com/forums/yanmar/220495-original-brochures.html
The title "original brochures" isn't really indicative or related to the majority of the content. I should have started a new thread.
I think you are looking for the old Advanced Search tool. If you click the SEARCH with the magnifying glass in the header and then select the "Search Single Content Type" tab it will give you the same filtering ability as the old advanced search.

i think they need to check on the spam filter as i have seen a few unwelcome visitors and their viagra or something spam emails. i dont think i ever saw one on the old system?
