If you're wondering how many characters are allowed in the Description field, it's easy to check.

First, go to the area where you can type in the Description field (navigate to a campaign, click on 'Submit a New Idea,' and locate the Description field).
Below it, you'll see a counter that shows how many characters you have left to type.

As you start typing, the character count will decrease, giving you a real-time update on how many characters remain.
