Adium And Friends With Multiple IM Accounts

I really love Adium, it's a great IM client for OSX which combines your GTalk, MSN, AIM, Facebook and Yahoo! contacts into a single list.

However, I found it a bit annoying having duplicate contacts in my list for friends that use more than one IM account, for example, a friend with both GTalk and MSN would appear twice.

To fix this, you simply need to add each IM account for that person into your OSX Address Book each with a different type (Home, Work, Other), and magically the duplicates are merged into a single contact.

Now, when you first send them a message, you should see a drop down in the chat window which lets you choose which IM account you would like to send message to.
