Question : Limit the number of attendee's to a class

We are trying to figure out the best way to use Outlook to allow users to sign up for a class that we will be having, but we need to be able to limit the number of attendees to each class.  What would you suggest we do for this?

Answer : Limit the number of attendee's to a class

If you are sending a meeting request, then I am afraid that there is no way you can limit the number of responses. All of them who get the meeting will have an option to accept/decline. I guess you will have to mention in the body of the meeting and sort the responses in the inbox to find who all responded.
