Dimdim is an easy-to-use, competitively priced open-source web conferencing app that we’ve covered previously here on WebWorkerDaily. Today, Dimdim announced the launch of Dimdim Webinar Edition, which allows for larger web conferences with up to 1,000 attendees.
Dimdim Webinar is very easy to use for attendees, as unlike other web conferencing products, you don’t need to sign up or install any software or plugins to join a conference. Hosts also don’t need to install any software, and they get access to an impressive array of features including screen-sharing, web site co-browsing, webcam video, text chat, audio and whiteboard tools. You can customize the look and feel of the webinar to match your corporate branding. Hosts can record webinars and get access to an analytics package for tracking who attended and how they interacted during the event. The app feels quite quick in use; joining an event is fast, and switching between presentations is snappy. Read the rest of this entry »
Last month I wrote up the new version 4.0 of one of my favorite free online meeting applications: Yugma. This application is a favorite among many WebWorkerDaily readers and writers. Version 4.0 brings a lot of conveniences, but I still had a few things remaining on my wish list.

Now, Yugma has just announced several improvements to its free and paid plans that can make a big difference for those who regularly use this application. At the top of the list of improvements is a fix for a bone I had picked before.

When things are free, the price is always right. That’s one of the great things about open source software, and many open source applications are now so mature that they compete very directly with proprietary alternatives.

Dimdim for Online Meetings. Dimdim is widely regarded for its ability to host online meetings including up to 20 people–for free. The latest version of this free, open source application added many new features including letting you record your meetings and share playback URLs.

Anyone who’s ever tried to collaborate live on the web with other people, be it making a presentation, sharing a desktop or just talking about what they see, quickly learns the difference between theory and reality. The theory is web collaboration is so easy. The reality is you need to jump through multiple configuration hoops, sometimes poor network connections and overly paranoid firewalls to get a hurky-jerky 256 color thing sort of working.
Enter DimDim. Its no-install web collaboration free Open Source shared desktop/whiteboard/PowerPoint or PDF presentation service works well via an Adobe Flash plugin. The Open Source business model allows for a free service (20 attendees max). But you may want to spend $99 a year to get the Pro service to customize the interface with your own logo and have up to 100 attendees. There is also an Enterprise edition with even more features.
Steve Chazin, Chief Marketing Officer (love that title!) of DimDim took me through a demo of the service that will launch next week.
