I have just been printing out our Chat histories.
Just opened up the Archive and printed the archive screen by doing a Print screen.
Then opening paint and pressing control V it showed how often my Wife and I Chat sometimes two or three seperate time a day. But it does not show any of the Conversations which lets face it no body but the two of us should be privy to.
So basically heres a step by step guide
1 Open yahoo messagner Archive in a full screen.
2 Have the list of the chat histories you want to Print, in view.
3 Then press ctrl or function and then print screen (will vary from pc to pc). Nothing will seem to happen don't worry.
4 You now need to open Paint or another such program.
5 Then simply press control V
6You should now have a Large print of your Screen. You may need to fiddle
around with the settings but for me i just opened paint and pressed control V.
7 Save the Bitmap file and you have a list of your Chats.
This can be printed or emailed as required.
All anyone can see is a list of your Conversations, not the content.
