Away

From BitWise DocuWiki

Setting away status indicates to other users that you are not currently able to respond to messages. When you go away, you may want to enter a short away message. What you include in your away message is up to you; some users use them as a mini-blog, some users leave detailed information about their whereabouts, some users display quotes, etc. Messages sent to you while you are away are accumulated so that you can view them when you return. When you are back and ready to send messages, you should set your status back to Available.

You can optionally let BitWise set you away when you are idle. Idle time is the amount of time that has passed since you last moved the mouse or touched the keyboard. See Away / Idle preferences.

BitWise also offers extended away messages that are stored while you are offline.
