Currently every Wednesday from 8.00PM there is a weekly group iChat session. This may change to a mid-month chat instead. To join the chat, within iChat, simply go:
File/Go to chat (and enter 'kesmug').

A couple of tips:
1. To view all the participants of the chat, chose
"Show Chat Participants" from the View menu

2. To show the name of the buddy, chose
"Show Names and Pictures" from the View menu

We are about to start holding themed chats focusing on a single topic each time. These discussions will be saved and available exclusively to group members via the forum.
