I've blogged about the savings you can achieve with several LotusLive offerings, including:
LotusLive Engage. The LotusLive Engage service includes all of the services of LotusLive Meetings and Connections, and adds to that online forms and charting capabilities.
LotusLive Meetings is $60 a user/year, and LotusLive Connections is $84 a user/year, so a subscription to both for an existing Lotus customer would be $144 a user/year. But LotusLive Engage is only $120 a user/year for an existing Lotus customer. So not only do you get all of the savings I've document for Meetings and Connections, but the savings are greater because of the lower licensing fee, PLUS you get the additional capabilities in Engage. To get the form and charting capabilities available in Engage from a premise-deployed solution, you'd have to deploy Lotus Forms Turbo, and those licenses alone are $2,060 for a 20-user pack ($103 a user, plus servers, storage, etc). So with Engage, the savings keep adding up.
The forms in Engage are extremely easy to create through the browser, and once again, you get the benefit of being able to make these forms available to free guest accounts.
Two other nifty additions you get with Engage are the integrations of your Meetings with the other services. First, you can pull files from your LotusLive Files repository to present in your meetings.
Another integration is with the Forms service. This anticipates that after many meetings you may want to get feedback on the quality of the presentation or event test attendees on what was presented. Easy enough, just click 'Start Survey' when you're done with the meeting.
