Question popup dialog box

to access certain forum, a dialog box (containing a warning message) is displayed with 2 buttons for yes (to proceed to the forum) or no (to return to main menu or upper level).

pls advise if it is possible to achieve.

I didn't understand of what you would like to have (inside article discussion).

Is this message in a wrong category?

There's no pop-up warnings in Kunena. You either have access or you don't.

i want to implement a confirmation dialog box before entering a forum. the dialogbox contains yes and no. if yes, go directly to forum, if no, return to main page or whatever.

one example of this use is to confirm the age of visitor before accessing adult info.

pls advise how to achieve this.

You can actually do this by writing some custom javascript. You just need to bind the dialog box to the submit action and do the logic in there.

The question you asked is not really related to Kunena, it's general question which has a general answer somewhere in the web. Google something like "mootools dialog box".

I've not done this before, so I don't have answer to your question.
