Questions

Straight answers

What qualifies for Academic Free?

A non-profit academic event or a community event that is free to attend, with up to 50 speakers and 5 sessions. Commercial and paid-registration events use the Conference plan.

What if our pro bono event exceeds the Free limits?

Talk to us. For example, a 122-speaker pro bono conference would normally fit the Conference plan, but may receive a Free exception after a quick conversation.

Is the Conference price a subscription?

No. The listed price covers one event. There is no recurring subscription unless we agree an organization-wide arrangement with you.

Do Free events lose important features?

No. Deadlines, access controls, file rules, version history, invitations, reminders, exports and retention controls are part of every plan.

What happens to materials after the event?

You choose the retention plan: remove materials after the event, after a set number of days, on a specific date, or keep them available. Protected backup copies may remain for up to 14 additional days.
