I find that using MSN log style is better than the direct copy from the chat. Example is
here. You can then do all those find and replace and change color stuff. But I find this style is much easier on the eyes.
If anybody wants to do that, go to you log, then copy down the chat, it will be in a table format. Delete the columns you don't need, and then select table, convert table to text. Pretty easy to do.
