Adobe is also providing free 90-day trials/access to Connect, which is their web conferencing service. This is available to individuals and businesses and educational institutions. The trial limits the number of people who can participate in a web conference.
Be very careful to read the license agreements and any information on terms before accepting the license. It is your responsibility to cancel the trial before it ends if you do not intend to subscribe. Adobe automatically starts billing you once the trial ends, and Adobe also automatically rolls subscriptions over each year. Most subscription plans have an introductory pricing that is only good for the first year; the price will increase after the end of that year.
