I want guest must register there name before viewing full forum ...

Means see this two images..

first image main forum name

and second one image for topic of that forum

ok guest view this...  

But after that if they click on topic that show they must register before view that topic..

Admin's CP - Users - User Group - Guest - [detail] - Access Level: 0

I try but this not work...

I think it works.

Forums - edit forum - [edit] - Perimission (No Select to default): View: dont choose the Guest.

Yes .... This work...

Thanks..

u r welcome.

But if we do as you told, the whole thread will disappeared if they are the guest.

Is there any other way we can do?

If i want the guest can see the thread, see all the topic.
But if they want to click on the topic to see inside....no more to see.
How to set?

I know reading access can do but it should be setting one by one.
Some of my member don't know how or forget to set!

First go in Admin CP
In Admin's CP -> Users -> User Group
in User group go in System Group

There you find Guest .. Click on Details.
In details check Access Level in Basic Permission
Make Access Level 0

After that go in Forums
Click on Edit which forum you want to edit.
Go down and you see Perimission (No Select to default)
Dont select any check box ..
So Guest view your topic but not read any topic details.

oh.. that is!!!!

That's what I want !

thank you very much!!

Real Thanks to ann because he solve my problem..
Thanks ann..

And special thanks for Karma
