GizmoProject www.gizmoproject.com (Windows | MacOS | Linux)
Gizmo competes with Skype to offer free, peer-to-peer, over-the-Internet phone and video calls, but uses open standards.
Gmail www.gmail.com (Web | Mobile)
What to do with nearly limitless e-mail storage space—that’s the enviable quandary of Gmail users, who can store up to 5.5GB worth of e-mail and chats. And the amount is constantly growing. Other perks include advanced search options, real-time updates, and “conversations,” in which e-mail chains are stored in one continuous thread for easy perusal.
Mail Redirect http://addons.mozilla.org (Windows | MacOS | Linux)
This add-on for Thunderbird lets you bounce a message to the proper recipient without revealing that you got the message fi rst.
ooVoo www.oovoo.com (Windows | MacOS)
ooVoo video chat is more P2P than Skype (no supernodes!), with a better picture. It supports up to six co-videoconferencers, fi le transfers, and group text chat.
SightSpeed www.sightspeed.com (Windows | MacOS)
SightSpeed has better video quality than ooVoo, but in a less attractive interface. More than two video chatters will cost you, as will file transfer and group chat.
