I have recently just created a new site and its a free webmasters resource website that has free scripts, free tutorials, articles, forums and a whole lot more!
I am currently looking for anyone that would like to contribute anything they have already done. I have no problems in including links to your site or even a reference box.
The website is brand new so it doesnt currently have a PR but eventually we estimate it to be PR5 or higher, so eventually your link back will be more valuable.
If you are interested, simply PM me.
