Still hunting for a Google Wave invite? You’re not alone — and in fact, there’s a whole community springing up just to meet your needs.
Google Wave Invites is a free “marketplace” for distributing Wave invites, much like have sprung up in the past for Gmail and other popular invite-only beta web apps. If you need an invite, simply sign up with your name and email address and cross your fingers.
[UPDATE]: The site is apparently being pounded with lots of traffic now, by a raging stampede of Google Wave invite seekers. If you can’t connect at the moment, try again later!

If you have invites to give out, you sign up with the site and get a list of those still in need of access. Once you’ve distributed your invites to people, they are marked in the database as having been invited and dropped from future “needs invite” lists.
It’s a simple and effective tool for distributing a scarce resource, and is friendlier and easier (not to mention cheaper!) than resorting to scouring eBay as has happened in the past for other high-profile beta invites as well.
Have you gotten your Wave invite yet?
