Michael,
>>The Dashboard is listed first in the row. I just grabbed the second
block, the one labeled, "Main", and slid that over to the first
position. Bingo! Apparently users land on whatever is in the first
position of the menu item row.
You are absolutely right here. Your solution will work perfectly if user signs is using the ajax sign in form located at the top right console.
What Omari referred to is the page where users land when they sign in using the direct URL :
www.sitename.com/sign-in . Right now if users sign in using the form located under this URL they will always end up on dashboard.
