Third Party Viewer Directory/GroupTools
GroupTools is a text only client with a small set of features compared to many other clients. The main focus is to make SecondLife residents experience with group activities more barable since sending multiple notices and IM's can be a hassle and very time consuming.
A few other features are available as well, and more might become available in the future too. GroupTools is based on the OpenMetaverse library sourcecode
