I'm sorry but I just had to laugh. Your post just kinda said to me, "Please let my dad join. He's not a complete blockhead! I swear he knows what he's doing!!!"
Either that or it's kinda how one of us leaves the computer for a few and tells the others, "My kid/husband is going to play for a minute. Just in case they do something crazy, you know it wasn't me!"
ROTFL!!!!
Admit it. You want to get him addicted so he doesn't cut you off!
Kidding! Kinda.
Of COURSE your dad can play with the other adults!!! Why don't you post, or have him post on our Secret Friends thread. That's really the first step right now. To find him some adults to play with. Then tell him to keep an eye out for new events on this thread. Or, if you have a particularly onus task, you can or have him post here to request a particular event!
And tell him one of our first rules is: HAVE FUN!!!!
