Thank you all for the warm welcome! Ranger Ron, I have suggested to my son that he join, but at the moment he seems to be too caught up in bonding with his unit to have time for any online stuff, unless he sees that guys around him are here, too. (Then again, why would he want to join any group that accepts his dad as a member?)
We'll see what happens. He's been there all of two weeks, so he's still settling in.
