Scenario:
- I have installed Wordpress MU in localhost (local computer).
- I am using Windows XP Operating System.
- I am using WAMP Server.
Problem:

Generally the wordpress 404 page contains one or two sentence saying that the page is not found. But you can make it more user friendly. Instead of just writing plain text about page not found, we can display archive list and a search form. In this way, the visitor can search or browse your website instantly. This is a nice way to keep your visitors within your site.
I got this idea from wp-comfy theme.

Here is the procedure to create a custom archive page for your wordpress blog.
1) Create a file archives.php
2) Write the following code in it.

Twitter, Facebook and wordpress are all popular and fascinating. You publish an article in your wordpress blog. And you may want to publicize your article in twitter and facebook through status update separately. It would be very easy and time saving if I could publicize my blog article in twitter and facebook as soon as the article is published.
But this is possible and I have implemented it as well. You just need a wordpress plugin and facebook application.

I was thinking of a wordpress plugin for google adsense that would make me easy to add adsense on my sidebars and on my post. I did search for a flexible one but could not find any satisfactory result. So, thought of making one by myself.
I just created a simple wp plugin named ‘Quick Adsense’. This plugin is in production phase. It is not full fledged yet.

I just created my first wordpress plugin. This plugin is useful for displaying author/admin information in the main page body, in sidebar, or in every post.
The plugin is named “Author Intro”. You can add the title and text (brief introduction) to display your information.

Suppose you want to show your google adsense in the top-left side of your post. If you simply put your adsense code in the single post page (single.php) of wordpress then the text of your post will appear below the adsense.
To solve this problem, I used stylesheet property called ‘margin’. The example below is from single.php file of my wordpress theme. The adsense code is kept in between the

Suppose, you have many sub pages (child pages) of a single parent page. You want to show the list of all the child pages in the parent page.
You can show the list of pages and sub pages in the sidebar of your wordpress theme with the addition of in-built sidebar widget called ‘Pages’. This will show all your pages and sub pages nested inside parent pages.
