People here are talking about why Dortmund have this flag and scarves-thing while we don't and are blaming it on ticket-prices. I have always wondered why there is no culture for this in Great Britain, and to be honest I don't think ticket prices has anything to do with it.
The thing is, that Die Gelbe Wand and many other supporter-stands in Europe are quite organized groups (Ultras) which attend the games. The supporting groups cooperates with the clubs to make the best possible atmosphere, and the club usually "gives" determined blocks, sections or stands to theses groups. Often you have to be a paying member in a supporter club in order to stand in these sections, and the leaders of the groups often supply these supporters with flags/banners etc.
I reckon the 1882 Movement as a positive initiative, which in the future also could operate as an own supporter club with it's own sections in the new single-tier stand. This is of course up to THFC and a good cooperation with the supporters.
I don't mind lower ticket prices though, but to say that prices are equal to atmosphere is kind of a false argument.
