This is a simple plugin that sends a message to a user as soon as the user logs in. There is no configuration interface for this plugin, just install it and modify a few properties on the Openfire Console. Editable properties include:
plugin.motd.skipUsers : A comma seperated list of users not to send the motd to
plugin.motd.subject : The subject used when sending the motd. On some clients this will not be seen.
plugin.motd.message : The message body of the motd.
This plugin was written with legal warnings in mind.
