We're happy to have new folks!
If your clan castle is empty, be sure to request troop to defend you better against attacks. We really try hard to be generous with troops. If you find you need to use them during an attack to push you over to the win margin, go ahead and do that.
One more member and we can declare a clan war on someone. That's a part of the game that most of us have not experienced, so we're looking forward to it. I'm laying odds that my wife will be the better attacker in the clan, but we'll see.
