Welcome to the new version of MovieLens! After seeing how successful
MovieLens has been for the last 5 years, we decided that MovieLens needed
a makeover. There were several changes we wanted to make to the recommendations
we generate, and there were many suggestions to the user interface from
MovieLens was getting old and difficult to properly maintain. This new
version of MovieLens should be faster and better for users, and it is
easier for us to maintain and to deploy new experiments.
Yes. Everything from your old account has been moved over this new version.
All of your ratings and your To-See list should be just as they were before.
All of the users in your MovieLens Groups became MovieLens Movie Buddies.
Huh? What happened to my Groups?
Groups became Buddies. With groups, you could only get recommendations
for an entire group. This was a drag for groups larger than two people
when not everyone is there. With buddies, you can select only the people
who are actually going, which is much handier (we think!).
When we switched over, we converted any groups you were a member of to
buddies. Every pair of people in a group became each other's buddy.
Except... if a group member had chosen to hide their recommendations,
we did not automatically convert them to buddies, in order to protect
their privacy wishes. You're welcome to invite them back as buddies by
clicking the "Manage Buddies" link once you have logged in, but in the new version
of MovieLens, users cannot hide their recommendations from their buddies.
One other note: if you invited someone to join a MovieLens group,
but they had not yet accepted, these invitations were not
converted over. You should use the "Manage Buddies" feature
to re-invite them. Sorry about the inconvenience.
More info on buddies is available in our help files. Let us know how
you like buddies compared to groups!
I never used Groups before and now I have a Buddy named 'Test Buddy'! Who is he?
In order to show users how easy it is to use buddies for recommendations, we have given
each user a test buddy. This test buddy is named Test Buddy and has, in our opinion,
a rather electic taste in movies. We invite you to try getting group recommendations with him
and see what you think. If you don't like him, just go to the Buddy Admin page and delete him.
Are there any changes to the browser requirements for MovieLens?
Yes. We no longer support old web browsers, including Netscape 4.
Supported browsers include:
For more information, please see our MovieLens Browser Requirements page.
Why? (I like my Netscape 4!)
Because Netscape 4 and other older browsers have very buggy and incomplete implementations of important
web applications, such as MovieLens, very difficult. As such, we chose to limit the browsers we support.
Plus, if you upgrade, you might find that many other websites will also start looking a lot better too.
I was a beta-tester for this new version of MovieLens, and I made
many changes to the movies I rated. Did you move these changes over too?
We would like to thank you again for being a beta-tester! Your comments
were very valuable and we attempted to integrate all of your suggestions
and comments into this version.
At the end of the beta test, we asked a survey question if you wanted
your changes from the beta version of the site to propogate to the final
version of MovieLens. If you answered "Yes" to this question,
we did move all of your changes to your ratings to this version

Unfortunately, the PhD student working on the mobile versions
of MovieLens has graduated and at the moment we have no
other students who have time to pick up and maintain the
project. There is a small but steady stream of emails
requesting that we get this feature going again, and we'd
like to do it, believe us! We hope that it will return at
some point in the future, but for the time being, it is
unavailable. We apologize for the inconvenience.
