as many people say that you can only hold 30 to 10 people in one discord call if you were to make a server and add a chat or a VC you can hold up to 99 which is more than zoom and you can also use the text chat, general chat or anything else that you add and the best part you can hold pretty much infinite people I have personally seen servers with up to 100k people in it. One of the better parts is that you don't necessarily have to download it you can search it up on google and make an account it's as easy as that. Another thing is due to the original purpose of the website/app is that it's very customizable meaning that your students can customize heir profile pictures and names, but not to worry in a discord server you can have it where only you can change their nicknames so let's say things get too confusing or you want to be able to see who they really are you can just change it to their name. One last thing I will say is that you can have customizable ranks and so on so if you desire to split people into teams you can do so and with that, you can customize what they can do like give people ranks or de-rank them. Like I mentioned earlier about VC's you can also screen share and do videos so you can see their screen or their face.

we were using slack and at the same time we had a subscription with office 365. after a while we hit the slack free limitation quota. and it got annoying. the search ability was useless in free tier. and more annoying whenever you search, it opens a webpage and doesn't do it in the app.

on mobile there were many cases that I didn't get notification of important discussions. rooms was the way to separate a talk. but it become tedious. each time for a new subject that you wanted to discuss, you needed to add all the team members into a new room. and after a while the room goes silent. you will end up with a tons of not-in-use rooms that you don't want to clean up them for history purposes. also the slack UI for sub discussion is very stupid. if someone forget to check the checkbox to post the subdiscussion in the main discussion thread, other team members even won't notice such discussion is in progress.

we was paying for office 365 and thought why not give the teams a shot. we won't be in worth situation than we are. we moved to teams and we loved it instantly, we had a separate tab aggregated all the files upload. we could reply on other talk. no need of creating a new room. this way room belongs to a team and not a certain topic. our sub discussion was visible to the whole team. enjoyed integration with azure and unlimited history. the best part was integration with outlook. it was a full suit solution. our stats become busy on outlook meeting events. we get weekly analyse. we didn't need to host our wiki seperated. we've created wiki per team. the communication was much more fun.
