Module development and code questions

I've seen some other threads about AdSense revenue sharing, but seems there's no modules that do this yet. I have a website and I want the users to be able to enter their AdSense publisher ID so that on their blog pages a % of the time the Ads will be under their ID. I don't know PHP much, just enough to get by on tweaking things, but I'm not sure how this would be done.

I know there's hacks out there to do this in vBulletin and such. Can anyone help me out?

I set the publishing option to

Show this block by default, but let individual users hide it.

Page specific visibility settings
Show on every page except the listed pages.

However, whenever I logged out, my news aggregator doesn't shows?

Hi
we are a final year project group from pcce,and are developing a confernce website using drupal,we have thought of using the ecommerce module and were just wondering if anyone would assist us how to go about using the ecommerce module,need help soon,dead line is near 21st jan 2006.i wanted more information on the tables created by eccomerce module....

I've written a couple modules for a fairly busy site (about 3000 unique visits per day) with almost all users being anonymous. I'd like to make sure I've done everything correctly to ensure that Drupal's built-in caching works properly with these modules. However, I can't seem to find anything on working with the caching mechanism in the Module Developer's Guide. The cache table in the database appears to have entries for the nodes based on my modules, so things seem to be working, but I'd really like to be sure.

I took a sample Php code for doing dynamic text replacement and made a module for Drupal.

Here is the original code:

It works really nice since you don't have to change your content to use it. All you have to do is enable the module and all your headings turn into nice looking images.

Unfortunatelly you also have to make some modifications to your template to use it. Just a few lines in the template.php

Hello,

My Clean URL is installed and is working fine but I have a search page that i'm passing parameters through (in the URL) that needs to be cleaned up...

My URL currently looks like: ".../search_real_estate?City=A&Bedrooms=B&Bathrooms=C&Min=D&Max=E" (where A through E are the variables that i'm passing)

Is it possible to ammend the .htaccess with a rewrite rule that will not mess up Drupal's Clean URL functionality, and will make my urls into something like this:
".../search_real_estate/A/B/C/D/E"
