It was a really cool instant messaging program. It supported aim, icq, yahoo, msn, and icq. It was way cooler than trillian and free. It featured the ability to find other odigo users who were at the same website as you were, it featured the ability to change your mood and interests so you could find people with the same moods and interests. Among odigo being a multi-instant messenger, it also had it's own messenger network which was actually a lot cooler than the other IM services out there. It was also the perfect way to talk to strangers at any time. I used odigo from 2000 until 2003. It was a really fun messenger, had a nice interface, and ****, i talked to so many people from all over the world with it too.

For a short time in 2004 Odigo Messenger allowed users to use the service to talk to users in other IM networks, but the feature was discontinued at the beginning of 2005, presumably for legal reasons.
After further review through massive googling you'll find that to be sort of innacurate. It just sort of vanished without a trace but did remain functional even up until 2006. I'm curious if it's still functional. I found one place on the net with a tweak to a config file that points odigo to a different server (where odigo was probably temporarily moved over too) and retained on and off functionality. Sometimes it worked for a couple of months and sometimes it didn't. Idk, if it's still going on or not. I want to find information because it's interesting.
