Zitat:TLF WelcomeAd is a flexible and easily customizable welcome banner on display for users with a configurable post limiter to set who see's your display banner. You can set in your AdminCP a post count limiter which is set as a minimum amount of posts someone needs to reach before the official welcome banner/ad goes away for new registrants.

This is kind of like their temporary official reminder that they are welcome to your new community and is a great way of managing new community welcomes as soon as a member joins your forum!
