If you need to search for something specific you can go to Google and type disboards: Put in the the words you want to search on after the colon, like "breakfast" or "All Star Movies pool" or even your own username and it will only bring up search results from the DIS. You can further refine the search by clicking on Search Tools and Any Time to select a time frame. I actually find that more useful sometimes. No, you can't get just all of the "New Posts" but this will at least help you with your trip planning and to find threads you have posted on.
With a board this size, or any internet forum, things have to be adjusted and updated to keep them functioning at their best.
