AnyMeeting is a Java-based meeting space that supports up to 200 attendees. The basic, free version is ad-supported and is limited on the features offered. Paid versions remove the ads and add additional features. AnyMeeting is PC and Mac compatible, but I would imagine Linux gurus can get it to work there as well. Video conferencing is limited to 6 streams. AnyMeeting has all of the standard features of a web conferencing app plus some additional ones like polling and a status indicator interestingly labeled “My Mood.” This app even offers an integrated “ticket sales” module so you can charge admission to your webinars.
