Before you start

I know that Drupal 7 is more than capable of delivering a multi-user, multi-site blogging service. However, my time and resources are somewhat limited, and I'm trying to determine how much work would be involved in creating (and supporting) a service that meets some not insignificant requirements.

Would a community website similar to formspring be possible with drupal? User sign up and question/answer interface? I'm guessing this would require custom code for the questions and such but would this be cheaper and safer than working from scratch? How hard would it be to make this seamless?

Dear all,

I am looking for a contrib module that allows me to do something like this:

Hello Community.
A friend of mine and i were having a discussion and this site Drupal came up as a site i could get code modules for doing different stuff. I.e. Im trying to get code that lets me log unto a website. I've been poking around...downloaded and installed drupal for my pc.
But im still wondering where to go to find code an whether i could try it on my stand alone website thank you

Do you think it would be possible for me to make a file hosting service such as rapidshare or megaupload using Drupal?

We are going to redo our website. I am doing the products research and decide which one is the best for our org. I would greatly appreciate your advices/opinions if you could help me get some more understanding about drupal's capabilities.

Here are our requirements:
1. membership management. we are a membership based org, and need a integrated DB to manage/track our members info (mostly done by admin)
2. registered user management. Different from membership management. users can sign up on our website and get some benefits: such as subscribe newsletters and get emails etc.
3. permissions control based on the users roles. for example, org members can download files for a certain event, but regular registerd users cannot
4. e-newsletter: edit and distribute emails based on the subscription mailing list. and also need to achive these newsletters based on the categories and date/issues
5. e-calendar: events/calls announcement. admins able to add descriptions and upload files, send email reminders. registered event/calls users be able to download files/materials. After the event/call expires, they should be archived along with the descriptions and materials/files based on the categories and dates
