How to Register

Webinars will be hosted through Zoom. You will register online and Zoom will send a unique link to the webinar of your choice.  Do NOT share this link, as it will be used to verify your attendance. You will need to join the webinar via computer.

Payments will process through PayPal. Look for the option on PayPal marked “Pay with credit card.” You will need to register separately for each webinar you choose to attend. The link for each webinar will be different.

If you have any trouble, contact the OACFA office by email and ask them to re-send you a link.


You may test the link before the webinar. It will connect you to Zoom and tell you the webinar has not started. However, this will tell you your link is working.

Each webinar will be divided into a morning and afternoon session, but you do not need to stay on line through the break time. Credits will be granted based on 1) the total time you were connected to the webinar and your participation in the “poll” questions. These will be brief questions launched periodically during each presentation.

During webinars the audience will not be on screen or have use of audio. You will still be able to ask questions by typing into the Q&A box.
