You can also open the address book with your Keyboard by pressing Alt and B together.
Also you can open it by typing either of the following in your status or channel window
/uwho nick nick
The address book allows you to save information about your friends on IRC, such as name, email address, personal website, IP Address, and other notes. If you make any changes, you will see a yellow sign above the [ADD] button.
Note Although you might get the impression that you can put any image format here, the picture must be in the standard BMP format, mIRC cannot handle any other picture formats at this time. Also its a bit buggy, if you right click on the picture, it disappears, even if you click cancel and reopen the address book.
Who is?This gives you the usual /whois commands information (Nick, Name, Address, Channels on, Idle Time, Away info, Servers, Status)
You can also do the usual ctcp commands
NotifyThis allows you to specify nicknames which you want mIRC to inform you that they are on IRC, when you're connected to an IRC Server. mIRC will inform you whenever a nickname joins or leaves the IRC network you are on.
To add a user just enter the following information and click on the [Add] button.
Nickname The nickname of a user that you want notify to look for.
Note An optional note or reminder that will appear next to the users nickname.
Play sound The sound that you want played whenever the user joins IRC.
Perform /whois This option makes mIRC perform a /whois on the user when they join IRC to look up their address. Note If you use it with too many nicknames then the IRC server might disconnect you for flooding.
Add/Update/Delete To add or delete users from the list. After you make a change to the settings of an existing user, you must click the Update button.
Show notifies in active window The default is to show notifies in the status window, however checking this option will also show notifications in the current active window.
Only show notifies in notify window This will make mIRC display notifies only in the notify window.
Pop up notify window on connect This will pop up the notify list window when you connect to an irc server.
Note:- Some IRC networks might let you use a full address instead of just a nickname, the only way to see if it works is to try out.
OptionsHere you can specify your email software.
Previous versions of mIRC had some difficulty in finding your default email software. I hope this has solved the problem.
