all new shoppers set to user group admin

[Inselwolf]

The list of my shoppers shows all of them with the user group administrator. This cannot be changed.

Is there a way to change them to another user group with less access rights?

I noticed that in the product description there is a little icon to the left above the product picture. Clicking onto it opens the product editing screens. This means, any customer can edit the product, which i (of course) do not want.

This is a Joomla feature...

Users->manage->select all you want to change -> batch -> delete or add groups
