Within your account, it will ask you for your Non-Profit name. Call it <TEST Your Organization's Name>. This way we don't inadvertently charge you for anything during your TEST period.

Creating a TEST account allows you to set up your auction and add test items for you and your team to create your auction page and custom link, view items, place bids, review outbid and winner notifications, etc.  This way you can make sure that our platform fits your needs.
