IS THERE A WAY TO DO THIS BY CHANGING THE SAVE LOCATION OR SOMETHING LIKE THAT ON THE MESSENGER SO I CAN HAVE ACCESS TO THEM FROM ANYWHERE WITHOUT HAVING TO DOWNLOAD PROGRAMS IN EVERY COMPUTER???? THIS WOULD BE A GREAT THING

If you could store the chat history virtually or in some site it would really help with the access and solve having them erased by computer crashes and stuff like that, but they should be stored directly from your messenger not through your computer because when you chat in different computers they wont all stay together this becomes a big hassle, hopefully microsoft listens and does something about this, maybe there already is something out there that im not aware of? if so help me out thanks
