I have a uni group assignment, and we want to have an online meeting and work on a word doc we have to create. Is there anyway we can have everybody looking at and editing a word doc at once while having voice comms and maybe text chat going? Like maybe have one person in control of the word doc and others can take over? Could even be a remote desktop type thing I guess - as long as 5 people can see it at once, and take over control. Is there anything like this?
