Module development and code questions

I tried to install the events module. I created the tables in the database and added the events folder in the modules folder. When I navigate to "modules" the page does not open. When I delete the folder it opens again. What am I doing wrong?

hello,

I've just installed the latest release of acidfree + patch for the filemanager.
I put the dir 'acidfree' in the modules 'dir'.
I activated the filemenager module, no problem. I activated the acidfree module, and I have plenty of warnings (=errors ?) :
warning: Invalid argument supplied for foreach() in /var/www/sdb/4/b/poulette1976/drupal.4.6.3/modules/acidfree/acidfree.module on line 113.

When I click on create content, I have the same message.

When I click on 'acidfree media', I have :
warning: Invalid argument supplied for foreach() in /var/www/sdb/4/b/poulette1976/drupal.4.6.3/modules/acidfree/acidfree.module on line 113.
warning: array_keys(): The first argument should be an array in /var/www/sdb/4/b/poulette1976/drupal.4.6.3/modules/acidfree/acidfree.module on line 1440.
warning: in_array(): Wrong datatype for second argument in /var/www/sdb/4/b/poulette1976/drupal.4.6.3/modules/acidfree/acidfree.module on line 1440.

When I try to create an album, I have a white page with the messages :
warning: Invalid argument supplied for foreach() in /var/www/sdb/4/b/poulette1976/drupal.4.6.3/modules/acidfree/acidfree.module on line 113.

I installed forward.module for drupal 4.63 and it's working fine, but it would really be great if the email that is sent could include the node/page title and maybe even a teaser/excerpt instead of just the url. I've searched for possible solutions, but can't find any previous discussions on it. I'm guessing that I need to get data based on the $nid and print it, but can't figure out how to do it. Can anyone help? Thanks.

I am using the 4.6 releas of the Stock Quote Module. Obviously, it allowes individual users (if so configured) to input their own stock portfolio. What I would like to do is have the administrator configure a "stock portfolio" that displays for all users in a block. Has this been done or any way do do this?

Thanks

I probably put this question in the wrong place.

Content on my site is for registered users. The Events module still allows access no matter what I do. I don't see Events show up under Access Control. Is there a way to close off Events for non-registered users?

I developed my first module and translated it (in french). But I note that the access permission do not appear in the POT file, and thus they are not translated in the access control administration page. How do I translate them?
I used the same syntax as for user.module:
