Well, THAT'S good news...!

To anyone that bemoans not enough threads about WHATEVER it is that piques your interest the most about arranger usage, the easy answer is 'the fix is in YOUR hands'.

Not enough threads about repertoire...? START ONE!

Not enough threads about technique...? START ONE!

Not enough threads about Brittney Spears...? START ONE! (OK, just kidding on that last one!)

But moaning about a lack of content, when YOU can provide that content, or at least get it started, is plain silly (and that is a YOU in the plural, this isn't aimed at Scott... ALL of us that SAY we want these threads but don't start them is at fault).
