Before you start

I am not sure I am posting this in the right support forum, so please bear with me. We have just downloaded the donate module that uses paypal. We are unclear on how to set it up with our paypal account and create the "donate" page for users to make a donation. Could someone please walk us through this? Thank you.

I am a php developer with about 3 years experience but i have not as yet customized a CMS. I am looking at several CMS both open source and paid commercial for the project. I have been asked to customize a CMS of my choice. Here is what i need to be able to do.
Everyone i speak to seems to be reccomending drupal, so i have come to you hoping you can answer the following questions.

(my apologies if these seem a little broad, but i am attempting to gather information for the first time)

1.All accounts to be searchable in a central pool

2.For individuals to be able to sign up/login/edit there profiles.

3.For company’s to sign up / login and then add users/delete (those mentioned in point 2), which they can manage ( these users are visible in the central search).

4)Companys would have access to different faculties based on what type of a company they are and what privileges that would give them.

5)A front page which displays the profiles of users, which can then be clicked on and viewed.

6)Would there be a problem displaying randomized records on the front page.

MORE QUESTIONS

7)Do i access to the source code ?

8)Do i have The ability to add custom records to profiles ?

9)Can the CMS handle a large numbers of concurrent users ?

10)Is the CMS logically laid out, commented and documents ?

I'm one of a group discussing a new website providing support for a FOSS package. I have got as far as beginning to lay out categories for a home page. The site will include a forum and I've set up a suggested model on http://www.createmybb.com/ .

Is there a similar service for drupal? I know there is a "demo" but that is just for trying the software. I want a site where I can set up a website model, not for actual use, just as a basis for discussion.

Hi all!
I've been tasked with developing a new section for a site that will allow customers to login and download their files. Each customer should only see their own files, and there are two types of customers who need to see two slightly different navigational menus.

Is Drupal overkill here? Is there another solution I should be considering instead?

Ok guys, bear with me here.

As I understand it, a forum post is basically an "article" (of some description) followed by a series of comments in Drupal.

What I can currently do in Joomla is insert a bot into content that prints "Discuss this article in the forums" in each article, which links to a forum page.

While in Drupal I'm happy to include comments on blogs and articles as they stand - and would prefer it that way - I'd also like "Blog Discussions" and "Article Discussions" to appear as "boards(?)" in the Forums page.

To build a website which has 100,000+ registered users... which is a better option using drupal or a framework? Can drupal support so much traffic?
