Do you have an old (Prior to February 2010) link to the Forum in an email? If you are looking for any threads from those links you can decode them like this:
This breaks down into:
Forum -> http://www.blackbus.org/forum
Subforum name -> /query-import-export
Thread Title -> /5039-copy-paste-information-into-raisers-edge-query-new-post.html
That takes us to this thread here. Hope that helps.
