I have been wondering if there is a way to make board's/forum's areas to be visible to the quests and visitors but not to be avaivable for their use (when they click the link to the certain area, they will directed towards "Log in" page and will be not avaivable to see what is in there, unless they aren't members of the board/forum).

Is there a basic code for that one?

acp>forum>categories and forums>

click the x/check icon next to the one u want to change read and write permissions on

Erm...

In fact, that will allow quests and visitors to access/read the threads that are in there and that is not exactly I want to have in here...

I want the quests and visitors directly go to the "log in" page once they have clicked on the visible area (which actually is locked/hidden and can accessed by user's password in order to see the threads/topics), not to let them see what is written in there unless they aren't logged-in members of my forum.

if you set all of your permissions to members only when guest click it they will be auto directed to the login page

That's the point of it! It is not directing quests and visitors to "log in" page, in fact, it is directing them to the area and its topics no matter I set everything to "members only" + it is showing the areas themselves if they are "member only" (they appear not to be visible to the quests and visitors though...).

Post the link to the area, so we as guests can see it.

please remember we need a link to your forum if this not gave we can not help you any more.

Thank you

There is no need to. I have actually solved the problem by myself in past few days and is all working now. 

Thanks for your assistance anyway!
