There are not enough current posts to require more than one page for the nanny share forums.
An automated script deletes posts from the nanny wanted, position wanted, and nanny share forums after two weeks. However, the script does not delete entires from the search index. Therefore, lots of posts that no longer exist are still indexed and come up in a search. The solution is to rebuild the search indexes, but this is a time and resource-intensive process that I don't do very often. At any rate, give the small number of posts, there is no need to search for them.
