I need to build a pretty simple volunteers manager web site and I want to know if WordPress is right for me and if so what do I need to change in the basic WordPress code and which plugins do I need to download in order to implement my web site.
Web site definitions:
1. There are a few categories. In each catagories there are several activites. Administrator can add and delete activities.
2. User can sign in with a user name and password and subscribe to categories of his choice.
User will get an email whenever a new activity was added to a category he subscribed to.
3. User can comment, upload photos, videos to an activity he subscribed to.
4. Administrator can send group e-mails to subscribed user by category.
