I still cannot find how to purchase a group membership or the cost. Also, I wasn't asking how many authors on a webquest, but how many users without buying a group membership. On the the screen shot that you sent me, the information is only if you have a group account code. How do I get the account code. On my account page, there is nothing about a group account, only that I have already purchased a Pro membership, and no information about how to purchase a group account.
