I've created a flash tutorial on how to make a userslist in CB:
www.notexa.be/joomla_tutorials/1._create_a_userlist_in_community_builder.html

At this time the player only works in Internet Explorer, sorry about that. Let me know what you think of this tutorial.
Thanks !

Update:

I've created a new flv player based on the player that comes with camtasia studio so that the movies also play in Firefox.

The quality of the movie is also improved. Now text is better readable.

Plays in FF on the mac great.

Grmbl, off course there had to be another bug. Now it played great in FF but not in IE

Bug squashed, so now everybody should be able to view the tutorials.
Could someone with Opera also do the test ?
