I'm considering a not for profit event publishing website for a local community comprising of over 1000 people.
The features I want to include are as follows:
1. Multiples users can add edit remove events with/ without admin approval. possibility of offering admin rights to loyal users
2. Location/ Country based events. IP address will be used to detect city and events and display accordingly.
3. Users of the website should have an option to subscribe to all , certain categories, or even a single event and sync it with their smartphone/ email/ outlook calendar.
