I use Instant Messaging a lot.  In fact, if you ever want to contact me and reach me the quickest, Instant Messaging is probably the way to go. I use Trillian because I can combine all of my accounts into one application and it works fine for me.  I have to sacrifice some functionality but that's fine with me. Rarely do I actually log into the native (MSN Messenger, AIM, Yahoo! IM) client.  In fact, I only have MSN Messenger installed on my computers. Today I was looking for an option in Trillian that I couldn't find, but I knew that it was in MSN, so I fired up MSN and logged in. One of the features that Trillian doesn't have is the ability to deliver messages that were sent to you when you're offline. As soon as I logged in to MSN Messenger a message window popped up.  It was a message from Ken that was sent to me back in May.  We had been having a conversation and he was sending me the answer to a question that I had asked him. It's just really strange seeing a new message from a friend who isn't with us anymore.
