Plugoo enables you to chat directly from your Instant Messenger with any visitor of your blog, personal webpage or e-sales site. When you're logged into your Instant Messenger (Windows Live Messenger, Yahoo! Messenger, AIM, GoogleTalk, Jabber or ICQ), you can receive in real time all the comments of your visitors or any question they might ask, and answer instantly! Very similar to the Meebo module, however this widget will email you msgs if you are off-line... which can be handy.

Note: You must create your widget at 'plugoo.com' --- it's free.
