Installed the Twitter Module earlier (on gertschepens.be) but was puzzled by the fact that there wasnt a block right away.
Luckilly, http://gotdrupal.com/ has a Video explaining it needs the Views module and how to do it all: http://gotdrupal.com/videos/drupal-twitter-module
I do have to say, the global user didnt really work out and I had to use the user settings, but other that that, its a very powerfull module! Another step in the gertschepens.be project š
