We've been using Blackboard
Collaborate since back when it was Elluminate (then Blackboard
Collaborate, and now Blackboard
Collaborate Ultra). The Ultra version is browser-based and very simple to use. It is typically used for office hours for our online instructors, handling virtual training sessions our team administers to our faculty, and other times people on our campus may want to meet virtually. Collaborate is also an easy way to have a guest speaker join a classroom remotely.
Collaborate Ultra is integrated with our LMS (Blackboard
, though they support other integrations), so essentially there is no setup involved for the faculty member. Students just click a link, type in their name, and they are able to join the session, simple as that. Smartphones and tablets are also supported.
The Collaborate team has been aggressively working on making the tool more and more accessible.
