Module development and code questions

I want to use Drupal to create something like Bloglines on my site - users have their own blogs (as Drupal already provides), and can choose whether to make these blogs public or private (which Drupal does NOT support). Ideally, I'd like users to be able to create their own personal "access lists" - people who can view their blogs.

HI

How do I raise the limit on the maximum number of characters allowable in a blog title? A number of the scientific articles I blog are cut off at the knees, since they are a tad longer than the current limit. Can I raise the limit to 255 characters?

Thanks for your help.

I am looking for a bibliography module that maintains a bibliography comprising of books and papers.
Each bibliography will item could have the following attributes:
Title, Author, URL , Abstract, Publication Location, Publisher, Publication Date, Volume, Issue, Pages and notes

I want to display the entries in a tabular format and allow the users to sort on title, authos, publication date, and
date added.

I want a button in the form like this (not a submit button but a button type button):

<input class="form-submit" name="op" value="New" type="button">

I use this code:

 $form['New'] = array(
  '#type' => 'button',
  '#value' => t('New'),
  '#weight' => 19,
);

....but I obtain a submit button like this:

I'm trying to modify the display of my event calednar in list form to include the location. My PHP knowledge is very limited, but I'm trying to use "$node->event_location" to call up the location using this line:

  $output .= '<div class="location">'. t('Location') .': '. $node->event_location ."</div>\n";

This brings up "Location :" in the listing, but nothing more. I'm using the event module with flexinode and I'm at a loss as to what string I need to call up to display the location.

I know several people have been looking for a module that allows single sign-on for these two apps. Just ran across a post at coppermine.net that has some help:
