I am looking for some help around customizing a list from SharePoint front end as I do not have access to a SharePoint developer.
We have a Nomination Form for Awards (custom list). The Awards forms are supposed to be submitted before 10th of every month. After which, the users should not be able to add new items in this list. I need help from you all on how do I get this done!
One way is to manually change access rights for everyone from Contribute to Read, but this is rather risky option - user groups painfully created for 5000 users may be get accidently deleted.
