When Users are registering the forum, there are some information showing up in the page. Which page I can fix the registering page? Please tell me where I can find it.

Go Admin CP. --> Basic Conf. --> Register & Access --> this page to set the Register things.

But I still don't get the item that I need. I want to find how I can change the registering item.

ah, sorry.

If u mean the rules,

Register & Access --> Display Registration Rules: yes
                         --> Registration Rules: put the rules in.

Thank you very much
but I found more question about the registering page
because I want to set up another one and it will be Chinese interface.
I hope my use will understand it and also I want the users to know which item is necessary to  fill in. so how i can do it
Sorry I have a lot of problem

sorry dear. bt it only can have one register page.

If u want to set a Chinese interface, i think u can post the Chinese items below the English words.

As,

"The English rules"
         .......
"The Chinses rules""
         .......

Sorry I mean How I can change the interface into Chinese
and also I have no idea to setup and see the level of member

2. the level of the member group. go Admin CP. --> Users --> User Group --> u can see the level here.
