The ability for students in different parts of my school district (both public schools) to take their classes together via web conferencing is very useful! I have no dislikes about this software at all - it's easy enough to use even if you're new to online teaching/learning but yet flexible with advanced features like video recording which has made our lives easier since we've been able to record lessons without worrying so much about equipment issues.
It would be helpful for teachers who want additional support from other educators by having them present during live sessions instead of using email alone-but not necessary. Just make sure your internet connection allows multiple users simultaneously accessing through remote access devices such as laptops etc.-this feature doesn't work properly otherwise when there are too many people trying to connect remotely at once.
