Text chat allows the user to save all text conversations as files. You can enable this feature in the chat options. A file named "maintoc.htm" will be created in the specified directory and will contain links to the Text Chat logs.
In case of any log file saving errors the text chat will display an error message. If that happens, make sure the specified directory exists and that files inside it can be created and accessed. Some programs (such as Microsoft Word) prevent other applications from changing files that are open, so be sure to close any log files after viewing them.
