I have created a program which runs inside a Internet Exlorer browser window that normally is used by Skype developers that displays chat messages.
The chat names listed in this program, are listed by most recently created.
Once you click on a chat name, if that chat had any chat messages, you can right click in the second window under "Message Info" and "Select All" then "Copy" and "Paste" the chat messages into notepad, wordpad, or other word like programs and save the chat messages.
