Thank you for your quick response.
The problem with all the redirects that I have found and tried, is that they redirect only after a login. I need it to automatically redirect individuals that open the page that are already logged in.
That is to say: guests who type in and go to http://www.thiswebsite.com go to one page; while members who will automatically already be logged in, go to another page.
Redirects don’t seem to work for this purpose. I hope my problem makes sense to you.
