Is there an Access Table for the Webcast Portal?

I'm an STS and in preparation for our Stake Conference, I have a couple people at each building who are responsible for setting everything up, (projector, TV's, etc). They'll also need access to the Webcast portal.

A few of the people in these calling aren't called as technology specialists, but as building specialists, and i'm worried they won't have access to the webcast portal. Is there an access table I can view, or is there some way I can grant them access to the portal? Or do they already have access and i'm just missing it somehow?

Any insights are appreciated.

Off hand, I don't think they need access. Just the link to the event you've set up.

I don't know the complete list, but we have all my assistants, including those assigned to support webcasts at receiving buildings, in the stake position of Assistant Technology Specialist. When they log in to the portal they appear to have the same access as I (the STS) do.

But as Russell says, you can send them the Congregational Link from the Event Setup page. After supplying their church account credentials, they should see the list of saved locations, from which they can select.

From the Meetinghouse Webcast 3.0 How-to-Guide (PDF), we find the following:

Connecting the Webcast to Receiving Locations (page 19) wrote:
2. (a) Congregation Link: Use this link for your meetinghouses and other locations where large congregations meet for the event. An STS or assistant at a receiving location will need this link to set up for your congregation to view the webcast.

It doesn't say that an "assistant" needs to be called to anything special to use the link.

3. You can click the Copy button next to the URL link and then paste it into an email to send to the STS or assistant. Or, if your assistant at a congregation location is an officially-called Stake Technology Specialist (STS) or Assistant STS, they can access the Viewing URLs tab themselves and click on the View button to directly launch the webcast media player in a browser.

This makes it clear that no special calling is needed if you use the Congregation URL (just an LDS Account, as explained later in the PDF).

Gone is a predetermined list of your helper's LDS Account usernames in the Meetinghouse Webcast Manager. Now any valid LDS Account login can be used, which I prefer immensely over the list.

Yes, other's responses are correct, you do not need to be a called an Assistant STS or STS to use the "Congregational" link. The Event Manager -STS will send the link to anyone that needs it to setup the receive site, they just need to login to their LDS account when they click on it. Also, if your helper/assistant happened to be officially called as an STS or Assistant STS, they do have access to the webcast portal, and alternatively to receiving the link, they could login to the portal and click the link themselves.
