Hello,
Usually WebEx or gotomeeting are the main ones. There are also some alternatives like anymeeting you could check out.
I've used WebEx in the past - in a different lifetime (different company) and I really like the interactive feature such as having the participant "raise their hands" (there was actually a hand icon that they need to click to show that they are raising their hands) when they want to participant or have a question they want to ask or clarification they would like to make. I do not have any experience with gotomeeting, although, I saw they they have a free trial, so I can try that out.
Does anyone have any experience with
omnijoin? I've seen banner ads about this and thought it is worth the look. I am very interested in the how these sites can allow for interaction for the training - oh and by the way, when using these, do I still need to have them dial-in to a meeting over the phone? That is also something I want to avoid. It want to have the meeting / training completely on the site with no need for phones - minimizing telco costs.
