Hi All

Thanks in appreciation...

The easy answer is DONT.

Many users hate it, most browsers will automatically block pop-ups unless it is generated by a users click and you only serve to hide your content from the viewer... let them see what you have and if you really need to say something then say it on the home page or put a link through to it.

Don't even get me started on splash screens
