a special part on the forum : "ABBA Albums" with a board like this : Ring Ring Waterloo ABBA Arrival The Album Voulez-Vous Super Trouper The Visitors Compilations and Live
where you can talk on the official releases (lyrics, singles, music...)
"ABBA Albums" board is for Materials and the board "ABBA" remains for everything else about the group.
For new fan and curious who discover ABBA it might be easier and maybe more serious ? And of course easier for the fans because you don't have to search when you wanna talk specifically on a album and materials related to it.
