I have noticed that the Google site search has not been returning search results for GUS forum threads but only for pages other than the forum. This has seriously undermined the ability of users to find the information they are looking for, I am sure. This problem should be resolved now and the search should be returning forum results within the next few days. The same problem that affected the site search also affected google searches in general, causing the GUS forum, previously heavily indexed by Google, not to be indexed at all. It may take up to a week or more for things to return to normal.
Sorry for any inconvenience this has caused,
