Yahoo!IM also comes with History feature. However when you first start Yahoo!IMm the History feature is not activated. Go to Tools and select Message Archive, then your history feature is activated. There are setting however on Yahoo that allow you to delete message archive after a set date. You can reset this to none, so your history will always be there.
MSN does not have a History or Archive feature. But you can download MSN Messenger Plus written by Patchou. It logs your MSN messenger in two different way depending on your choice–log by date, or log by each contact list. It also allow you to remove the banner from MSN messenger. Warning: it only works for messenger from version 4.5 to 4.7, don’t use it for version 5.
And don’t download version 5 at all, the word goes, M$ put a lot of spyware in it.
Your ICQ archive thingy…
I used to backup my ICQ history. I never figure out how to combine history db, but I the way I backup my message is to export them into text and keep it some place safe. Perhaps you can try importing the text:) Is there an import feature? I don’t remember…
