Here is another way to access the Seinfeld info in Rubens directory. Please foreward all other questions to him not me. :)
Get the page you accessed no problem (www.ifi.uio.no). Click the line that says "Ifi-studenters egne hjemmesider", an item under the headline "Studentenes eget informasjonshierarki". The page you should reach now is a list of all students who have created their own home page. Choose my name ("Ruben S=F8gaard"). The list is alphabetical after the surnames, so you should look almost at the bottom. Now you should reach my home page, and that page is in English, so I'll stop explaining here.
When you reach the page you want, choose "Add current to hotlist" from the Navigate menu in Mosaic. When you want to access it next time, just reach for your hotlist.
Let me know if there's any problems, or you can help me with the info I'm missing!
Happy webbing!
Ruben
