Welcome, back, Castle!
i don't know how long you've been away, but i'm sure you'll notice some changes - guys come and go - but - sadly, the more things change, the more they remain the same. variations on a theme. good to have you with us again, working on the common purpose.
"That you are here - that life exists, and identity; that the powerful play goes on and you may contribute a verse. . . What will your verse be?" Robin Williams as John Keating in "Dead Poets Society"
