“Jeder, der bereits einen SlideShare-Account hat, bekommt eine neue eindeutige URL, unter der er völlig kostenlos Meetings abhalten kann. Dabei stehen ein Chat, Bild und Ton einer Webcam und natürlich die Präsentation selber zur Verfügung, die man wie bei SlideShare gewohnt durchklickt, wobei die anderen Teilnehmer des Meetings ebenfalls immer die aktuelle Slide angzeigt bekommen. Es gibt keine Begrenzung, wieviele Teilnehmer an an so einem Meeting teilnehmen können.” Quelle: http://yuccatree.de/2011/02/slideshare-startet-conferencing-dienst/

Hier ist noch der Slideshare-newsletter, den ich in meinem E-MAil-Box gefunden habe: “Have you ever wished you could jump into an online meeting from anywhere? Or wanted to start meetings instantly? Well, guess what, now you can. No need to download software or wait five minutes for a meeting to start. Open your browser and with one click you’re in a Zipcast meeting.
Zipcast is the new meeting platform SlideShare that lets you conduct inexpensive, secure private meetings and limitless free public meetings from your web browser. Everyone gets a personalized meeting room – if you have a SlideShare login, you already have a meeting room at http://www.slideshare.net/USERNAME/meeting. Or you can get one for free here. You also get streaming video, audio and group chat for free.
As Rashmi explains here, Zipcast meetings are interactive and social and take place entirely within a browser window. Unlike older online meeting systems, no clunky screen takeover is required – you can keep other browser tabs open. You can invite people by giving them the meeting room URL via IM, email, Facebook, or Twitter. For a public Zipcast, chats can be shared on Twitter or Facebook.
Every SlideShare user has free access to Zipcast for conducting public meetings. Pro users get additional functionality like (a) ad removal, (b) private, password-protected meetings accessible only to people invited by the host and (c) audio conferencing.
Ready to Zipcast? Go to your meeting room to get started.
