In this FAQ:
What is Standard Text?
Standard Text is information that is applicable to all or a subset of listings. It allows you to enter information once and use it on multiple listings. It also allows you to update your text in one place and change all unsold listings and items without bids.
How do I add a Standard Text?
Step 1: Add Standard Text
Go to My GunBroker > My Account > Standard Text page and click Create Standard Text.
Step 2: Add a Standard Text Nickname and Text
Click “Save”. A nickname is a label that helps identify your Standard Text, and is for your reference purposes only. The Standard Text area is where you enter your information. This area allows for basic HTML use. Once your information is added you can preview how it will look on your listing by clicking the 'Preview' tab.

How do I add Standard Text to a Listing?
On the Listing page there is a Standard Text section that contains a dropdown with the nicknames of each Standard Text. This section can be preset using Item Listing Defaults.
Bulk Lister has been updated to include a Standard Text column. The Standard Text ID will be needed for this, the ID can be found on the My GunBroker > My Account > Standard Text page.
