Q: How do I change the URL in the Library Catalog portlet?

A: Go to:  /systemname/sitename/portal_skins/custom/portlet_librarycatalog

Q: TSLAC has set up the library's URL, we set it up with our nameserver provider, but it is still showing the "Welcome to Lostmaples root site" message.  What is wrong???

A: Nothing is wrong.  Go here http://www.dbswatch.info and type in the library's URL.  You will see that the URL is not yet pointing to the TSLAC server.  Keep trying for the next couple of days, and it should show up.
