Before you start

So, I'm trying to develop a web platform which will allow users to view and upload video, audio, images, 3D objects, and PDFs. The platform additionally needs to have social features like comments, groups, notifications, etc. I'm aware that it's possible to implement all of these features independently, but how they can be seamlessly integrated is what I've been trying to find out.

I know a bit about WordPress, Joomla, and Drupal as CMSs. However, I want to start a how-to manual project on one of these CMS and a little bit confused, which one is a best answer for my project. This is the example of a how-to site, I want to start. Please assist me, if it is a right choice for me.

Hi, as a church, we are wanting to do a 2015 Bible Reading plan together, and I was looking for a way to insert the document of our reading plan into some website, and then I can have it send an automated email with the daily portion of what is to be read that day? And people who would like to get the daily emails can subscribe or unsubscribe...? Is this website a good way to do that?

Thank you for the help- I'm researching this for my pastor...

I have an existing Drupal site with about 18,000 user accounts. The site is a subscription-based site and those subscriptions are currently managed by 3rd party software on a subdomain that reads/writes to the Drupal database to keep Users/Groups in sync.

Hi,

I'm creating a website with paid b2b membership. So the real user may not be the same who pay the memberships.

Here, what I would like :
1) Someone in the client company (director, manager) create a new group/entity (*) for the company.
2) Someone who can pay all required memberships create them (email of final users)and pay them of course.
3) Each final user receive an email notification to create a password and use the site.
4) Users in the same group/entity (*) can share informations
