[Zope] How user edit his account?

[Praveen Kumar]

Dear List,
        I would like to know one thing. I'm using exuserfolder to
provide the user accounts. While logged into the Zope application we can
modify the existing user account information. I would like to know how
user can modify his own account through web? If we hosted the site then
User can logged into the site by giving his username and password. Once
he logged in then he should able to modify his account. Please give me
some ideas.
