Where is the old UK stuff?
Using the "Older" link should bring you back one page of the approximately 8,000 topics on that board. Then you should keep choosing "Older" to go back to browse through older topics. If that option isn't working for you, please post on the "report problems" forum at http://www.chowhound.com/boards/show/40
If you are looking for something specific, first go to the International board and then use the search box. If you don't find what you want, try doing the same on the new U.K./Ireland board.
We are slowly, ever so slowly, by hand, moving the posts that were made before the new site deployment to their new, respective boards. We are doing this by working backwarks from June 23, so over time, more and more of the older posts will be in their new homes.
