Is it possible to give users panel access for a particular site, and hide all the other sites? I didn’t know if this was possible or not. I want a user to be able to send announcement lists, etc. for his domain–I just don’t want to share my entire control panel with him. Thanks!
Panel > Users > Account Priviledges
I’d suggest setting up a test account for yourself and playing with permissions so you’re sure you’ll give your friend the correct permissions.
