Module development and code questions

The modules available for Drupal are extensive and greatly appreciated. I am wondering if anyone is in the process of developing a newsletter module. This is the one glaring absence I see from the modules available. Ideally it would be one that allows a user to choose from multple newsletter types, while registering or editing their account and would also let them unsubscribe there. It would need all the other basic newsletter features like Html and text choices for sending as well as list management on the backend.

i see that members.module is posting e-mails of my users.
i think this`s not good, cause i promise users not post their e-mails anywhere on a site.

Who can i change this situation?

Thanks in advance!

Is anyone working on the upload of video or swfs?

Where there might be someway to have a media library of these files (including images, and thumbnails poss), meta-tagged, searchable, and also a way to embed them or link to them from other nodes?

What would that entail? Ideas?

I've installed gallery module on drupal. After that, the link
"gallery" comes between "home" and "photo gallery" on the initial page of drupal.
When I clicked on "gallery" Browser says that page is not found.
When I clicked "gallery" on the page, in the adress bar it writes that:
http://my_host/module.php?mod=gallery this link doesn't work.

I would like to write a module that uses the textile parser to make my node output all nice, without giving users the ability to post html. Textile is perfect for this, but it is not released under the GNU license. It is released under an open source license though, but I was wondering if there is any problem using it to write a module for Drupal?

Here is the license: http://www.textism.com/tools/textile/license.html

Would love to see Drupal have real workflow management. So any object can change depending on acknowledgement of a role. For example, user can submit request to become admin of site, active sitadmin sees request and sais "yes", might go to higher boss who acknowledges as well. then object is change is database or ldap server and user is admin.
