Can I create a sign up form that allows hundreds of collaborators?

I am wanting to allow teachers from across the state to enter groups from their class as options for volunteers to sign up to meet with them to read. Do you have the ability to allow that many inputs?

For each field, we allow up to 65,535 bytes, that is equivalent to 65,535 characters excluding Japanese and other special characters.

If you're anticipating to only have hundreds of groups which has few characters, then I think you will be fine. However, if you anticipate to reach that limit for a single question, you may want to add an extra field that your user could key in additional input.

up for those groups

Apologies for the misunderstanding. The most number of collaborators allowed is set to 100 per account, and that is available for our Gold plan.

If you have more than a hundred teachers collaborating, you can alternate them by simply removing a sub-account in order to free up a slot.
