It wasn’t for me, so I searched finally came up with a solution.  Since the solution is rather techie, I figured I would throw it up on here sans-technobabble.

Step 1

The first step is to figure out your username, the easiest way to do this is to see what is set after the slash on your profile page.  Remember this, you will use it later on.  Note that this could also be a number, you will use the number later on in place of a name.

Step 2

The next step, we start to create the account.  Go to your Adium account window by selecting Adium from the menu bar and selecting preferences.  Go to add a new account – like you would for any other account – and select Jabber.

Step 3

This is the final step, you are almost done.  All you have to do is log in, enter the information like you see on the left and click ok.  That’s it.  Quick and painless.
