Not so sure I'm going to download the messenger. My wife isn't a noob when it comes to computers. And she uses this computer often enough that she'd probably notice YIM and wonder why I downloaded it. She's not nearly as understanding as your wife. I'd probably be single if she knew about any of this.
Maybe I'm not as tech savvy as I thought I was. Yahoo Inst. Message, got that one. kik? Honestly all I have is that gmail account we used the other day.
