I understand a little Dutch, so here's a rough guide to the Dutch Annie Forum.
The picture at the top is of the 10 Annie's. Underneath that, the 'Welkom' box basically says that on the forum you'll find out everything about Annie and if you haven't registered, you should do quickly. There's there's one forum, with the site rules on it.
Under 'Annie Algemeen', the first forum 'Algemeen' is for saying anything about Annie that you want. It's worth a look as the top three entries inside it, pinned, are the playlists for 2005/6 and Efteling 2006/7. The 'Oproepje!' one is a rough version and an appeal for more accurate info.
In 'De Audities' (Auditions), there are several pinned (closed) posts. 'Ronde 1' and so on, describe what was required at each audition and the words are quite simple. The '...Screens' posts are pictures from each round. Very interesting.
'De Songteksten' gives all of the song lyrics. In the bottom pinned post, there's the full lyrics of each song on the amazing cast album, along with who performed what, as it was recorded live. In the other, there's the lyrics from the auditions which were totally different, as you'lll know from YouTube. The info box just explains that they weren't used again after the auditions.
The rest of the forum is divided into two sections. In the top one, all of the 10 original groups are listed by name. The top post in each one (pinned) includes the names and a photo of the group. Which of the five regions (Amsterdam, Rotterdam, Eindhoven, North or East) they covered and whether they were group 1 or 2 is also mentioned.
The other is layed out in the same way, featuring the five Efteling groups. Again, the top post in each one includes a photo and names. They all performed in one place but are referred to by region as the producers tried to keep as many girls together as possible, combining the two original groups from each region into one new group.
