It would appear that Gmail is ready to expand at a more rapid rate. Though account creation is still on an invitation-only basis, the invitations current users are granted have expanded. What has been 3-10 invitations at a time that we are awarded to dole out since Gmail started is now revamped. 
Logging into my Gmail this morning as my Gmail Notifier alerted me that I had an e-mail in my inbox I saw this new invitation box. Beyond setting my mom up with her very own Gmail account (finally able to tear her away from a certain company that goes by a simple three letter acronym), I don't know what to do with 50 invitations.
As with before, if you are interested just leave a comment if you're interested in an invitation. If you are worried about the internet boogeyman stealing your e-mail address I won't complain if you send me "name (at) domain (dot) com". And no, I will not use your e-mail address for anything other than sending you your Gmail invite.
As an avid supporter of Google and everything that they do, I am glad to see that Gmail is finally getting off the ground and they are opening it up to more users. It would be nice if I could look forward to a 2005-06 Google Fantasy Football League (hint hint). Add that and streaming audio and I will never have any reason to visit "the competition".
