You may participate in webinars/conferences several ways:
Webinars may be accessed online by going to www.join.me/christianbody. Some webinars are by invitation only and will require a special code to enter. Code will be sent to any who wish to participate. When you access a conference online, you may talk/listen by VOIP or by telephone, chat by text, and watch whatever is presented onscreen.
You may access voice only by using by telephone by dialing (213) 226-1066, then 248-714-534# for the public ones. Private webinars will require a different conference # which will be broadcast to those interested.
