This is probably silly...
That thing that I see when I click on "2-player Internet" that lists me and all other people online (I'm pretty sure that's called the tracker) is giving me difficulties. The only two times there have been other people around, I can't seem to figure out how to invite said person to a game. Am I (after asking, of course) supposed to click his/her name in th list? I can't figure out how to "chose a person from the list." Also, I was wondering if there was a way to keep myself available for a game in the tracker lobby while doing something else on my computer, for there isn't enough traffic to guarantee a game at a given time, but I don't want to just sit around all the time waiting for someone to show up.
