Before you start

I am looking to stand up a self-hosted Drupal system here.

I will have in the vicinity of 1500-2000 site consumers at max saturation time, with approximately 100 people in the roles of authors, publishers and contributors, with approximately 30-40 of those as concurrent users.

We are currently running CF9 on a Win2K8R2 server, running a fairly flat file system. We have outgrown our current flat file CMS and looking for robustness and a greater degree of automation that can be accomplished with Drupal and the additional modules available.

I want to make a website similar to this website http://www.sharedeal.vn, so I'm checking the best open source. And, after searching, I'm here. So, I'm a newcomer for this source, so I don't know if this is suitable or not to make this website with this source?

I am planning to work on a ecommerce system which is quite complex. Some of the needs include- bidding, social recommender system- reviews and rating, faceboook integration of user profiles, SMS gateway integration, online purchase of goods, comprehensive logging of events in the system. Also all the activites in the system are time based so there is a time limit for each type of actions based on actor permissions.
I was debating of using pure PHP v/s using Drupal.
Positives for PHP-
not a learning curve.
easliy maintainable.
Flexibility

I would like to know if drupal is a solution for us.

I would like to have this setup:

Hi,

First of all excuse me if my english it's enough correct.

I am studying the posibility to create a social community with two types of user. A free user and a premium account.

The premium account will have more permissions to operate than the free account and it have a cost per month.
I know i can manage it with ubercart.

I am unsure if i should use drupal.

I want to make a site just like this one:
http://www.tweetcatholic.com/

Will drupal support a site just like this?
I want users to be able to create an account and add themselves to the list.
Basically i want it to be a type of twitter database.

So, will drupal 7 do this? If so, what modules would i use to do this?

Thanx.
