Drupal 7.x

I am not sure if I should try doing this in D6 or D7, but thinking that this might be interesting to try both ways.
I want to create a customized proposal system for an Industrial Construction Project. Naturally, we don't want competitors to see what we are doing, but we are also looking for a way to setup formal proposals in a template solution.

We begin with a template, probably a template of a book.

In each book section the author can attach references to other nodes.

The finished Book would be en entire node that we could invite Prospects to see.

Just an outline:
Section Intro, would include an NDA that the client would have to agree with. Just not to show it to competitors.
section one would be a proposal outline with details
Section Two would include all details to qualify to compete on the project.
Section Three would include Nodes of past projects that we have done

I would also want the project to have limited access to just prospects, and probably time limited as well. So we can send an invitation to a prospect to view the project, but no one else except for internal people can view it. Then use time or limit viewing by IP address or something like that.

My thoughts on doing this would include:
- A Single domain, and assign Books to users. But need to get the right Modules for this.

Hi,

I want to display a custom form in a block.

My block:

function my_module_block_view($delta = '') {
  switch ($delta) {
    case 'my_block':
      $block['content'] = drupal_get_form('my_module_test_form');
      break;
  }

  return $block;
}

My form:

Hi, I am happy to announce that we have two openings posted on our jobs website. We are the Interactive Services group in Columbia University Information Technology. We design, build and maintain websites for schools, departments, labs, institutes, clubs, groups, projects and individuals. MOST of this we do using Drupal though there IS a legacy CMS system still in use for some sites called HyperContent written in Java.

Requirements for both positions are:

Hi

If I read the File API correctly, when a file_save() operation is requested, then a file is persisted to disk and then it file_save()'s associated hook_file_insert() & hook_file_update() implementations are called. Is this correct?

If this is so, then can is possible to prevent file_save() operation writing to disk?

Thanks

I'm writing a test of a function that imports data about users from a .csv file. As usernames are randomly generated for testing, I'm dynamically writing this file based on the generated usernames before uploading it. Naturally, I'm removing it before the test is finished running, but if the test crashes for some reason, the file will be left. Is there a way to specify a custom cleanup routine when someone presses "Clean environment" on the testing page that will delete this .csv file, or something else I can do to cleanly handle this situation?

I'm adding (with Field API) several extra fields to users profile page. I'm able to organize them in to categories A, B, C etc. Now I need to add subcategories inside these, because I need to separate some fields from the others inside category. Since there are no ways to add some kind of "static placeholder" or "title" field - is there any chance to add category inside other?
