Module development and code questions

I've installed the cvs version of cck. It's working fairly well. How do I add "previous page", "next page" links? I have my posts in as book pages right now and will have to convert them over. How do I add "add a child page" and "add a sibling page" links? I searched on google and drupal.org. I did not even find anyone who asked this question.

I needed a custom module for my website. I experimented with CCK module, but the whole body goes to front page as teaser. Then I experimented with Flexinode and I marked a field to be used as teaser and only one line from that field goes as a teaser and the rest is ignored.

Can any one help me to make one of these modules work with a teaser ( 5-6 lines ideally) or suggest another module.

BTW am on Drupal 4.7 beta 6
Thanks in advance

Thank you

Hi, I've been following the module developer tutorial, but I seem to be having a problem enabling the module I've just created. Here is the code:

I already asked this question but I am going to ask it another way to try and get some more responses.

This is something so simple it is proving difficult to search for. Within a PHP block or module, what would I put within <?php > to spit out the page's url?

For example, say I wanted a link to post this page to del.icio.us:

http://del.icio.us/post/?url=http://drupal.org/forum/4

the html would look like

I recently added a 4.7 branch for the Invite module. It has some new features and is more streamlined. There is a new API that lets other modules react to invite events. I used this API to make a buddylistinvite module that makes inviter and invitee buddies of each other when the invitee accepts the invitation.
