If you want to see the latest posts from all boards in a convenient way please check out /overboard/ Note: JS is reccomended to be able to post effortlessly, but I am working on a system where that won't be needed.
You can use quotation marks to search for exact sentences or phrases. Search will search for posts having all the words and phrases listed (ignoring order they appear in). Search is still work in progress but hopefully it will work satisfactory for now. Only the 100 latest posts matching search criteria will be listed.
