I'm with Irish Sergeant here - I like the idea that every time I think I've worked out the intricacies I find there's another clever dodge behind them. Like Levels in those Dungeon Type games my son used to play all the time.

I tend to use the DT index when I'm looking for a song - the Super Search gets too interesting and I get side tracked. I mostly use that to find old threads where someone said something I want to check or quote.
