Module development and code questions

Ive recently installed Drupal 5.1 along with Gallery however whenever I check on the status of the module installation and implementation I have the following errors

-"PHP memory Limit-Error"
-"Gallery 2 Location-Error"
-"Drupal Module/Gallery2 Plugins-Warning"
-"Clean Url/Url Rewrite-Warning"
-"Initial User Syncrozation-Error"

Hi,

I am trying to program my module AssignCourse so that Views could be used to create views using the AssignCourse content type (not a CCK node type).

This node type is based on the table, course_year. This table has course_nid as a field which links it to table, course. The course code and course title is kept in table, course.

Hi,

I am creating a website. I want to publish articles about products. I created a vocabulary and linked it to a node, product. If user wants to create an article for a product, he should select the product node type and select the product from the vocabulary that I created. This part works fine.

I noticed that the core module "Comment" doesn't allow me to NOT show the title of the comment. So let's say when I comment something like "I like your shoes", it shows the title "I like your shoes" and comment "I like your shoes." I find that redundant and cluttering, so I'd like to get rid of the title.

Is there a way to show just the comment? I played around with the module but with no luck.

TIA.

Would like to know if there's currently a (documented or undocumented) way to add/edit the fields in the Classified Ad content type?

I would like to add two text fields, and a tag field if possible?

Please help me to implement this registration process:

1. Registration page should contain password field - I am using ogintoboggan module.
2. User should confirm own e-mail - click on link in the letter.
3. User can login the site only after e-mail confirmation.
