Korero is a Windows desktop client for the Corrade scripted agent. Contrasted with other text-only clients for SecondLife, Korero is designed as a toolbox where tools are laid out and contained following a selection of areas such as "Friendship", "Land"...

Corrade is a multi-purpose, multi-platform scripted agent (bot) that runs under Windows or Unix natively, as a service or daemon whilst staying connected to a Linden-based grid (either Second Life or OpenSim) and controlled entirely by scripts.

It has many of the important features of Firestorm but runs better on some of my older computers (in other words seems to run lighter).
