The log file viewer will show you information on all of the last posted messages, and any errors that have occured. There are three levels of messages. The messages with a blue i are just informational, messages with a yellow ! are warnings, and messages with a red X where non-recoverable errors.

Double clicking any error will give you more details about that operation.

(Note: The most common error you will get is 441, this error is caused by the usenet server changing the groups they carry, or by you attempting to post to too many newsgroups at once. Try reducing the number of POST in the Manage Servers window for this server.)
