Link exchange with 3d design sites

We are looking to exchange links with high quality 3d design sites. Our site has PR5

Link exchange with insurance-related sites.

We want to exchange links with insurance sites. Topics: travel insurance, car insurance, health insurance etc.

Our site is co.uk. Need links from .com, .net. org. co.uk, org.uk

crosslinking and PR

Not sure when it happened but now Google sees the difference between links
http://site.com/
http://site.com/index.htm
http://site.com/index.php

So from now on we should use only one way of linking to the site root, otherwise Google will consider that these are different links. As a result you will get lower Page Rank.

Mask php mime type with htaccess

I decided to use .htm extension for the files and then process them using php:

Action application/
AddType application/

But problem is that php modifies normal filetype adding dynamic tags. Now I figured that it was better to have .php files and use mod_rewrite:

RewriteEngine on
RewriteBase /
RewriteRule ^index\.htm$ index.php [T=text/html]

Simple and it works! :)
