Thank you! Sorry for replying so late, but I stopped checking this thread after a week of silence. I wish there was some kind of notification when your post is replied :( That's a great news for me since I started programming in python :) I will let you know when I figure out something :)

No worries. There is an RSS feed for the forums:
