One Instant Messenger is a client that will allow us to gather all of our instant messenger accounts in a single interface, allowing us to manage each account separately and communicate with different contact depending on the protocol that we use.
The application is compatible with AIM, ICQ, IRC, MSN and Jabber, what's more, by a plug-in system we can add other services like Gadu-Gadu, Skype, Yahoo! or Netsend, among others.
Another of the appealing features of One Instant Messenger is its function to be able to work as a portable application (allowing us to take all our instant messenger services with us on a USB memory) or its capacity to be used as an RSS reader.
If you want an application with which to communicate with everyone, One Instant Messenger can be the tool that you were looking for.
