Resource

From PsiWiki

Unlike other Instant Messaging networks, the Jabber network allows you to connect more than once at a time, from different places. To do this, every time you sign in, you label it as a different "resource". A resource is just a name. You might call one resource "home", another one "work" and another - "laptop". You assign each of those resources a Priority Number. When logged in multiple times, messages sent to you always go to the resource with the highest priority by default.

For example: you leave Psi logged in at home with Priority 1, and when you're at work you sign in with Priority 2. As your Work resource has a higher priority, messages be routed to work when you're at work, otherwise to home. You sign off when you leave work, and messages then get routed back to your Home resource. If you're signed in at both Home and Work, and get called out to another location, you might like to take a laptop with you. In this case you might sign in as Laptop (Priority 3) for when you're off site temporarily.
