The bookmarklet tool lets you send Gmail messages with the click of a button so you don't have to visit your Gmail account. It's an application called GmailThis! From the developer's website, drag the GmailThis! link to the browser's toolbar. Then, if you are already logged into Gmail, just click on the bookmark and a Gmail applet will pop up with a link to the website you were visiting, along with any text you may have been highlighting. You may notice that the subject line is already filled in, as well. All you have to do is fill in the recipients and click Send. This is a quick, easy, helpful, and free application Gmail users will not want to be without.
