Hurray GRASS Team!! Out of the loop for just a little while and WHAT A MAGNIFICENT STRIDE in the Documentation!
Round-of-applause, Standing Ovation! Thank you. Just installing Mr. Kyngesbury's generous images on a new-to-me machine.
I will be looking for the Mr.Sid directions and R incorporation info this week (downloaded the Lizardtech DSDK, the Mr. Sid pug-in appears to either need activation or special call-to in SnowLeopard on this MacBook Pro (1/1,1)). 
Beautiful updates to the grass site - Hurray!
