Chat script
From Wikipedia
Back up of chat script: Via this option you can save the actual chat to analyse the data later on. Due to the maximum number defined in chat.php (presetting: 2000) this number of entries will be stored.
Delete chat scrap: If a user does not exit the chat via logout link, the alive-file and chat-file remain. They will be initialized due to a new start of chat, but can be deleted with this button.
- Tip: attention: The Chat scrap shall be only deleted, when no chat is active!
