This is just a word of advice to people in general. Don't post your messenger ID's on yours or anyone else's homepage. Those pages are public and anyone who is searching through members can get them. You never know who is going to pop up out of the blue on your messengers, and you will have no idea where they came from originally. My advice, if you want chat with someone in messengers, then give them your id through private messages, not on your homepage.

Also, I don't understand why people think that you are going to add them as a friend when they request it, and you have never chatted with them before. That is a stranger, not a friend. A friend is someone who you have chatted with and do consider a friend. Not just someone out of the blue. My advice there?? Tell them thank you and you will add them as a friend once you have had an opportunity to chat with them a bit, gotten to "know" them some. Then you can possible consider them a friend.
