This is a great time to use modern software like Zoom Meetings & Chat for video conference and meetings. I will try to go over all the features which I believe makes this software customizable.
You can use it either through a desktop, ipad or tablet, as well as your cell phone. The cellphone or other tablets may have limited features though. The thing I like the most about Zoom is being able to schedule several meeting, invite individual members to the meeting, either through a meeting ID number and password (optional) or a specific URL as an easy access link. I believe all invited need to have the software downloaded AND create a login. For training purposes, you can easily show your screen to your meeting members, so if they have a hard time accessing or understanding the information given to them, you can show them step by step. The host can also screen record the meeting to share with someone that wasn't available to attend the meeting. The host is the only one who can all members at once and individually mute/unmute. Everyone has the option of seeing a gallery of members on one screen or one person at a time (generally whoever is speaking). Lastly, there is a chat option included, but if you're on a tablet or phone you can't access the chat and see members at the same time. The chat is good to share links or information shared that you want members to access. Sorry about the list but they really have SO MANY OPTIONS.
The host MUST have a strong internet capability otherwise there may be some lagging so keep that in mind. Also, members that are accessing the meeting over a phone or tablet may have a limited amount of features, so I highly recommend a desktop (with camera) and hard internet wired for a more professional approach. I do believe they have currently waived the 40 minute max for meetings, but generally, I think you have to pay extra to have meetings longer than 40 minutes. This is not usually a problem, unless you have a very long meeting.
Meeting Security/Safety is another issue. I would HIGHLY suggest not sharing URL links online. ONLY SHARE URLS OR MEETING IDS DIRECTLY WITH WHO YOU WANT TO ATTEND, AND HAVE IT PASSWORD PROTECTED. If your meeting isn't password protected, it may be likely that anyone could access your meeting. The last thing you want is a stranger jumping into your meeting and roaming free on what they say or show. There are people like that out there, so save yourself the trouble.
