I created a register user. When I log in as a register user. when I click on the name, it took me managale profile page.

I want to disable that link. pls help. thx

If you want to disable the link remove the Register controls out of your Skin. If you're using a third party skin and can open the HTML files look for [USER], repackage and upload the skin.

If you don't have the HTML take a look at the section in the ASCX skin

<dnn:USER runat="server" id="dnnUSER" />

You could display the username through a number of other means, such as using Tokens within a Text/HTML module.
