There are two ways to create a scheduled Webex meeting...
From the Webex interface:
In a web browser, go to gcisd.webex.com then click the Sign In button at the top right. Click on the Schedule button.
Enter the meeting title, password, date/time, and attendees. If you want to provide additional info about the meeting, there's a place for that under the advanced settings (optional.)
Once finished, click the Schedule button at the bottom. A notification email will be sent to your attendees with all the meeting information and will also add the event to their Google calendar as well as your own.
Your Webex page will now show your scheduled meeting. When it's time for the meeting you simply click Start. Your attendees will have the meeting on their Webex page but the green button will be Join (instead of Start.) The alternative way to join the meeting is to just click the link in your calendar event.
From your Google Calendar:
If you need to add a large number of attendees such as your entire campus or department, this will be the preferred method because you can add your campus email list as an attendee. That's not possible in the Webex interface. Let's get started...
Create a new event in your Google calendar with the date and time of your meeting. Important steps: under Location enter @webex. Next click on Add Conferencing and select Webex Meeting. The first time you do this it will ask you to log in to Webex but will remember it after that. If it asks for your webex domain, use gcisd.webex.com.
Add your guest(s) to the list on the right then once you click Save Webex will create the meeting reservation details and add it to the calendar event. Your guests will receive notification of the event and it will be added to their calendar.
When it's time for your meeting, you and your guests simply click the link in the calendar event to join.
