I suggest that a change (or changes) be made to the adding friends process.
1. Change the label from "Invite Friends" to "Add A Friend" or "Add Friends"
2. Don't have "Facebook" as the default choice tab. The majority of people that play here don't connect via Facebook.
3. Instead of tabs, have 3 options after clicking "Invite Friends"
a. invite a Facebook Friend
b. email a friend
c. name search a friend.
The name search is an excellent tool. but in all the time I've been playing here, I never realized it existed.
in the past, I have clicked that "Invite Friends" button. All I noticed after that, was a "Connect to Facebook" button. There is wording about an "email tab", but I dismissed that, because if I wanted to invite someone whose email address I knew, I would just speak to them directly and tell them to go to Stratego.com. There is no mention of the people search tab.
Maybe it's just me, but I never realized those tabs were there. (They are off to the left by the way) I thought the only options were to click the " Connect with Facebook" button or the "X" in the top right corner to close the window.
