Pop-up message only for guest

First topic message reminder :

Hello,

Well, I just want to know If someone here knows a good script code or HTML Code that can I add in my forum to welcome all new people that visit my forum for the first time.

..can you explain it clearly..please..

This is an old thread.

You can use this now: Login Pop-up

Yes, it is possible to display messages that are only seen by guests. I know of a board that has two audio welcome messages on the homepage, one for guests and one for members. Doing something like this requires extensive knowledge of XML/DOM/javascript, and the ability to think outside the box.

duh..?? it seems not so cool..i want the script pop-ups..
i just don't know where to paste the code...
