Like I said, they've already reversed engineer the Hotmail protocol, the info is out there, all it takes is someone to make the plugin. SSL is required for the Hotmail protocol, so I wonder if Thunderbird has SSL support yet. If it doesn't, that might be an attribute to why there's no plugin yet. But if there is SSL support, then they better get crackin' LOL.
BTW, I bought an iMac and an iBook about a year ago, sold them, took a little break, now I'm back again with a new/better iBook than before.
