Could not post on his blog for some reason?

Rob,
Not sure if this will help with the URL problem you are having with your students, but here is a suggestion that I have used in the past.  I to have asked students to go to a specific website and they return only to tell me the site did not work when in fact they typed it in wrong.  What I have done is have them give me their e-mail addresses, which most of them have, and I then make a class distribution list and then just send out a website link.  The other thing I have done is to bring the class to a computer lab for part of a class and have them each log on to a computer, go to the website, and add the site to their favorites.  At my school the students favorites list is saved on their logon account.  Now I can assign them homework and all they have to do is go to any school computer and the site will be easily accessible and not reliant on their typing skills or lack there of.
