It would be good if the school has control on guest user account creation since the portal belongs to school and the account is being created without our knowledge. From the Admission portal, anyone can create a guest account which we do not want to happen at first place. We have to keep an eye on this daily to remove all the guests accounts. Its like an additional task.
Also, once the enquiry has been submitted, school should have option of what to show on the submission page. There could be hundreds of different reasons for this and it should be under school control to manage submission.
