does it cost anything to join yahoo instant messenger?

Yahoo! Instant Messenger is a free service. However, calling from PC-to-Phone (calling PC-to-PC is completely free; don't get the two mixed up) will cost money, and it depends what the cost is. The other services of Y! Messenger is 100% free. Just simply download Messenger or use the Web Messenger or Yahoo Messenger Beta. You can be on anyone's IM list, but you have to add them. To add:

1) Sign in

2) Click Contacts

3) Click Add a Contact

4) Fill in the blanks and change the network if you are adding someone in MSN (you can add MSN users).

5) Click Next

6) Fill in the blanks

7) Click Next

8) Click Finish

9) You have just finished sending a request. If the request is accepted, you can see each other online and talk to each other.

Yes, you can IM MSN (or Hotmail) users. Yahoo! Messenger and Windows Live Messenger have a feature that allows Y! users to interact with Windows Live Messenger users. Simply add the Window Live Messenger users with a Y! account with the instructions above.

No, Yahoo! Messenger is free. You can message friends on your "friends list". If you have their Messenger screen names, you can message them to get permission to add them to your list, and give them permission to add you to theirs. There are 2 ways to message people using other messaging programs.

1. Download each one of those instant message applications.

2. There are messaging applications that allow you to message people on any one of those applications from one place. You'd have to find out what those are. It'll pull up your friends' lists from each one. But you can't do this from Yahoo Messenger. From Yahoo! Messenger, you can only message people who have it also. Many of your friends probably have it anyway.
