Yesterday we told you that Google Wave was opening to 100,000 regular folk at the end of September, but on closer examination, it looks like Google's already allowing users to get in line for their invite to the limited preview.
Just head over to the Google Wave's sign up for updates page, enter in your email address, and select the Enlist me! option (you should be willing to actually report bugs and give feedback if you select this option) and sign up. After that, it's a matter of waiting and hoping you were one of the first 100,000 to sign up. Now you could just anxiously twiddle your thumbs until September 30th rolls around, or you could obsessively watch our Google Wave highlight reel and hands-on Q&A for the next couple of months.
