Some features, such as attaching files to messages, are available only with that server. WebBoard's administration interface is extremely convenient. If you have administrator privileges, you can access it from the Options screen. There you can modify user and conference settings and work with the logging feature, which Version 3.0 improves by allowing per-board HTTP logs. All of Version 2.0's strengths remain.
Users can attach files to messages, and administrators can forbid attachments or limit their sizes.
And WebBoard has a spell-checker you can use before posting a message.
