Module development and code questions

Currently I am working on setting up a community using Drupal. I've done quite a bit of work, but one feature that I need is the ability to censor certain URLs.
I pretty much want to stop members from posting URLs linking to certain sites.
I suck at PHP but can do a bit of work in it, so if someone could give me a bit of a shove in the right direction, that'd be nice.

Hi,

I'm searching for a module that enables text section selections for comments as is possible in Adobe (if you rollover the items the feedback pops up) or the Word version (a line from the section to a comment box). I've googled it, but haven't found the right module yet.

Would any of you be so kind to tell me if it exists and what the name is please? It's for a community for text reviews basically. I'm working on an IIS server :s. (If anyone has advice about possible crashes because of this, let me know!)

Following this doc I wrote a function mymodule_block to define block. Then I went to Drupal admin and found that admin block disappeared. Function code is below. What did I do wrong?

I am trying to do something like:

$cckname = 'field_test_path';
$node->$cckname[0]['value'];

I am not quite sure what syntax to use to pull this off.

All help would be great.

Thanks!
