If you use IM a lot, you probably like to turn on the history feature available in most IM clients so that you can go back and find things later. While the history function in most IM clients is nice, if you use multiple IM clients (one for your cell phone, one for your computer for example), you end up with multiple repositories for your history. This makes finding things harder since you then need to remember where the conversation took place, or else search multiple IM history repositories.

IM History is a new, free, service that aims to fix this problem. They allow you to log all of your IM history into a single place, even if you use multiple IM clients. This way, it's always easy to find the old IM that you are looking for, no matter where the conversation took place.
