No. If your organization has many GiftTool accounts, it’s important that you never login to 2 or more GiftTool accounts at the same time.
Because a browser session is established when logging into GiftTool, there is a risk that your browsers will get confused between both accounts. The trouble is that you may be over-writing your work into the wrong account when clicking save; or viewing the wrong data when looking at your reports.
Instead it is best to login to one account first, complete all your activities including running reports, and then log off and close the browser before opening a fresh browser and logging into the next account.
