I like freeconferencing also. Teleclass leading can be a book in itself, but here are a few tips.
Prepare prepare prepare
Give attendees a ground rules of telclass attending
Make your point and make it again
The more the merrier
Don’t teach, focus on the learning
Class title max 20 words, catchy and intriguing
Keep the class discription to 100 words
Know your audience
Plan at least 3 weeks out
Include instructors credentials, name and background
Know your style, peppy, warm, engineer type etc
Is it free?
Make registration clear and explain freeconferencing
What do you want them to know?
What are the benefits of your tele? Feelings
Enough for now
