I use AdiumX - just started last week, after I got fed up of the constant kick-off on MSN Messenger, the non-updating of contact lists, slow messages, and lack of features (Display pictures, for example). So, I Googled and came up with AdiumX, you can use skins (I have a brilliant Tiger one, to match my new OS, the contact list literally 'floats' on your Desktop, and can even be set to fade after a period of time. It's a great App. with all the extras you need, however it still doesn't do webcam. If you need webcam support I advise you use Mercury, although this is not a friendly program, unlike AdiumX that intergrates smashingly with the new Tiger (Which b.t.w is also amazing!) Hope I helped in a round-about way! :-)
