There are many ways to do so. You could, for example, change one user to use the new theme and leave the default to the other users. Then use a different two browsers to log in with two different users to see both themes "at once".
Of course, you should never develop on a production server. I do it anyways sometimes, but you shouldn't. Maybe at least you make a snapshot of your current database and files using Backup and Migrate.
good luck

We have one theme, Marinelli working but it has no easy way of adding regions so I want to use mpFree which seems to provide all the attributes I need. Question can I leave the marinelli theme working and on line while developing the mpFree theme.
If so how can I switch between themes to see what needs adjustment. Both would use the same database and content.
I'm stuck and would appreciate assistance Thanks Roger -- [ Drupal support list | http://lists.drupal.org/ ]
