We've written about the free, open source online conferencing application DimDim before, and, like our buddies at WebWorkerDaily, we like it a lot. Up to 20 people can participate in a meeting in the free version of the application, and the feature set is as rich as many paid conferencing solutions. Today, DimDim version 5 has arrived. Here's what's new in this version, including security enhancements and better performance.
DimDim version 5 features improved screencasting, webinar widgets, registration reports and is faster and more secure. The reports, in particular, will be welcomed by many people who do commercial webinars and the like, because they can gather information about meeting attendance and attendees.
 
 The improved screencasting includes a zoomable viewer that allows participants to view a presenter’s screen in full-screen mode inside their web browsers. Webinar widgets in DimDim 5 are designed so that they can be shared on social networking sites, and other places, for promoting webinars. Widgets automatically change to indicate when a meeting is live and can deliver recorded meeting content when an event ends.
There are also many performance and security enhancements in DimDim version 5. The application automatically recognizes webcams and microphones, and the company claims that DimDim uses less bandwidth in this version. You can also share videos and the like with meeting attendees, not just static web pages. DimDim is used by many businesses, who will appreciate the trusted SSL security features.
DimDim Pro is the paid version of DimDim, and it allows for easy recording of online meetings, and screen customization (graphs, etc.) for things like commercial webinars. DimDim Pro users can also have 50 attendees in a meeting, while 20 is the limit for the free version. The Pro version is $228 per year--far less than a subscription to a paid provider such as WebEx, although some enterprises favor WebEx because its meetings are hosted on its own secure network.
At DimDim's home page, you'll find a widget that allows you to sign up for an online demonstration of the new version, to take place Tuesday, April 7th at 10:00 a.m. (I believe that's Pacific Standard Time, although the widget doesn't say so). You can also view a four-minute YouTube demo here.Â
