calendar/events edit

We need somebody to check why when we post a new event in our calendar, it is not being displayed. Also, we need an admin section to be created for events, so admins could approve/decline the event before it goes online. Also, we need the admin to have an ability to block the poster by email/IP. The calendar with a link to the events is on the right side on the [login to view URL] website. All work should be done offline. We will send you all the files required, but will upload them to server ourselves. Preference will be given to those who will be able to finish this ASAP.
