Gandhi, as has been pointed out several times, there was a long thread in which everyone already gave their congratulations, well wishes and best (or worst) road advice to Josh. Folks didn't feel the need to do so again when you happened to find out/decide now's the time for you to send your congrats. You should probably chill some...no worries, man, we all hope thatguy has a great time, makes some big bucks and comes back loaded down with tales he can share.
No one criticized you for saying congrats, you started in on "everyone" else for not joining you.
