If you have multiple computers, and switch between them frequently, keeping track of IM conversations can be a hassle. Skype is one program that gets around this by providing you with your chat logs when you sign onto a computer, even if the conversation happened on a different machine. Trillian seems to have taken note of this, and has added such a feature to their IM client.
I’ve been a Trillian user for many years, as it was one of the first pieces of software that would let me chat on multiple accounts without downloading various messengers. This latest update has made it even more powerful, keeping track of conversations from different computers as well. It will even save all of your conversations to the cloud, should you choose this feature. Sounds like a win to me!
