What is the best webinar service for recording and archiving?
Are you looking for something free? Or you don't mind paying a few bucks? If you don't mind splurging a little, I would recommend trying out Anymeeting. They have three different versions that you can choose from. There is a free version, a version that has a ll the features for up to 25 attendees, and a version that has the same features but it can support up to 200 attendees. But if you want something free and simple to use, I would suggest either Skype or ooVoo.
If you're still having trouble deciding. We have a Top 10 Webinar Software report right here.
Hope this helps! Feel free to come back to ask more questions if you need it.
