For users of MSN Messenger, try the new version of MsgPlus! Works with the beta as well. Messenger without it is shit, really.
personally i think this is the best thing that ever happened to MSN, even though 99% of the reason i use it is just to kill the advert banner on MSN*
*i'm still amazed just how many incredibly annoying 'flashing' advert banners make their way onto MSN's advert space
i might actually try the msn beta now, as i allways refuse to use any version of MSN that doesn't have the ads disabled. :D
