Module development and code questions

hi people of drupal.

i was wandering 'cause really interested, is there any module that allows the user to "chip in" the content (means, to get "points" from posted contents on a certain site perhaps?

it is a bit strange to explain, let's make it like this:

as a user i have the possibility to post content and get me some "points, chips, coins. whatever and that this would be as an option while posting content.

Hello.

Does anybody have any clue on why I'm not seeing items in the "Fields" section when I add a view? (my first view) Are there any dependencies on other modules which were not mentioned in the documentation. By the way, it's on my dev environment.

Thanks.

Recently I tried to install the exif module to my dupal site. Now all I get when I try to log in is a page with the error message shown below. Can anyone advise me how to fix this?
-----------------------------------------------------------------------------------------------------
Parse error: syntax error, unexpected ']', expecting '(' in /mounted-storage/home20a/sub001/sc19994-YGXQ/starnet-tv.net/drupal1/modules/exif-5.x-1.1/exif/exif.module on line 52

CCK text field (no Maximum length is set, and teaser and full view is - Plain Text) is trimming automatically when the node is "promote to front page".
And the trimmed value is saving automatically into database.
How can i avoid this?

I'm trying to figure out how to get data stored in a user's profile using hook_user. I've got the form showing, but I can't seem to get it to actually save it so I can retrieve it later. The API docs don't show a full working example, and I can't find a good one anywhere. Can anyone help me with this? I just need an example showing how to store a value and retrieve it later. If anyone knows of any modules that do this in an easy-to-follow (LOL) way, it'd be a huge help if you could let me know. I spent close to four hours getting absolutely nowhere with this yesterday.

I'm using the ahah framework in a node module, but the fieldsets are not collapsible ('#collapsible'=>TRUE). Is It a bug?
thanks
