First Visit Message
This plugin shows a message on your weblog when a visitor visits your site for the first time. They can either click the message away, or push the button ‘Do not show this again’. After pushing the button, there will be added an entry to the database which makes sure that the message won’t show up anymore to the visitor with that IP-address.
Everything is fully configurable via the WordPress backend.
