Every time you modify a post slug, add a new post, rename a category, or otherwise modify any of your post and page permalinks, jadedcoder Sticky Permalinks (jcsp) will keep a copy of the original permalink along with the post or page it originally led to. If anyone tries to access the old URL, they will be redirected right to the new one, no matter how many times you’ve changed it.
If you re-use a URL that has already been used in the past, its copy will be replaced and it will safely link to the new article instead.
Don’t throw away valuable URLs! This plugin lets you re-organize your site as many times as you want, without risking traffic loss.

Keeps a history of your permalinks no matter what changes you make on your site, and redirects old links to the new ones.

Selectively add social network buttons such as digg, sphinn, etc to your posts or theme design.
I wrote this plugin because I wanted finer control over where and which buttons 
were placed on my site and in my posts.
Sometimes I have marketing posts so I want to link to Sphinn, but sometimes I have 
technical posts so Reddit would be a better choice. This plugin is flexible enough that 
if you want the same button in every post, then you can still modify your theme very easily 
to accomplish this.
You may place as many buttons, in as many places in your posts as you like.
This plugin handles: 
– Digg 
– Reddit (all button styles) 
– Delicious 
– Sphinn 
– Dzone (all button styles) 
– StumbleUpon
<h4>For Your Posts</h4>
Use the following in your posts: [SB button 1, …, button N]
Here’s an example post…
<pre><code>Hey, check out my new buttons!
Here they are: [SB digg, delicious, reddit]
And look
Here's some more:
</code></pre>
 [SB reddit, sphinn]
The different button types are: 
– digg 
– delicious 
– reddit 
– reddit1 (same as reddit) 
– reddit2 
– reddit3 
– sphinn 
– dzone 
– dzone1 (same as dzone) 
– dzone2 
– stumbleupon 
– stumble (same as stumbleupon)
<h4>For Your Themes</h4>
<pre><code><?php echo sb_make_button('digg', 'http://www.alexpooley.com') ?>
<?php echo 'I'm in a post now:'.sb_make_button('reddit', get_permalink()) ?>
</code></pre>
