hi @curley,
After about the third student we are all unable to get access to the project? Is there a user limit for each project?
I'm sorry you had trouble with this. We do not currently have any limits like that. Did your students see any error messages, or did the projects just not open?
If you posted this immediately after running into this problem, you may have encountered an issue we had with the service a little over 3 hours ago. System status can be found here: https://status.rstudio.com/
If this was indeed the cause of your issue, your students shouldn't have any trouble opening projects now. Can you please try again?
Also: if your class is going to have 50 students in it and you're planning to use a space for coursework, you'll likely need more capacity than the default space gives you (10 members and 25 total projects). To get more capacity, please go to the Projects or Members page of your space and click the “Request More Capacity” button, fill out the form that appears and submit it. We’ll get a support ticket with all the info we need to upgrade your account.
