From the top bar we can change password navigate and search. On the sidebar are Event calendar Noticeboard and Many other features, most of which visible only to administrators and not for other users.
In Complaints and requests page there are two parts, current pending and already done or resolved.
Any issue marked done by any user carries the information forward with the time at which it was done. These pages are searchable throughout, with every information from date to name is searchable. All the visible(even the searched data) is downloadable as CSV.
Admins can delete complaints edit to change the group of a complaint to assign it to the desired users. also Admins only can edit any request to change the date and time of any event, as in Registration form in frontend, it is possible to register an event only 24 hrs before. so this place admins can change the date for any exceptions.
Admin features
Manage users and groups feature is only for admins. In Manage users the admin can create or edit new users, give them hirarchy priorities, assign work(by selecting the group that user belongs to) define designation as to be shown on the frontend website in Infocell Team, and also can make a user inactive for not able to login, but still have all the complaints and requests completed by him in the database.
