You can do that by logging in as admin, them from the Admin-User Accounts, select the "User Settings" you have 3 options for "redirect after login" and "redirect after logout" and "reditect after registration" you can select any tab from the site for this redirection.

I do this for my site but the changes don't stay.  At the top of the user settings screen, I have the following messege:

In this section you can review the membership provider's settings. Some providers may allow you to edit the settings. The default provider based on the ASP.NET MemberRole requires you to edit web.config, so the settings can not be updated here.

I am not a programmer so I know very little about how this works.  My web hoster has been of no help either.  Do you know how I can get these changes to stick or what code to put in the web.config file?

Thank you!
