Being into web design for 6-7 years, I've created quite a few websites. Below is a list of sites (that I can remember) I've played a role in creating (and/or still run today).
Tau Online is the first proper website I have created, and I still run it today. It's a fan-site for the hobby Warhammer 40k (produced by Games Workshop).
It currently receives around 30,000 unique visitors and 3,000,000 page views per month.
PHP Mission is a brand new site that I've made, which houses tutorials and forums for PHP newsbies and professionals.
I was comissioned to re-design the site What's My User Agent? in mid 2007 (and write the site's content). The owner of the site and I agreed to a blue Web 2.0 layout, and I feel this was achieved well.
EcoGasaver was another site I was commissioned to make - it sells a product that reduces the fuel consumption of cars and larger vehicles. A darker layout was sought after due to the site's main audience being young adult males.
Tristan Da Cunha is a website I made, housing information about the remote island Tristan Da Cunha. I seen the domain name TristanDaCunha.org for sale, and I just had to buy it!
Flash Games Allowed is a flash games site, with over 1,000 games on it!
The Land of Jokes was a relatively large project I worked on in the summer of 2006. It was released into the public domain in November 2006 and quickly grew. By mid 2007 it had over 2000 jokes and funny pictures on it.
I sold The Land of Jokes in early August (07) hence I no longer run or maintain it.
Futuristically.com is based upon a free RPG script called Dragon Knight, however it's been heavily modified to be futuristically themed (as apposed to the usual 'bow and arrow' job that most RPGs have).
Due to time issues I never fully released this site (i.e. advertised it properly), however I'm in the process of selling it to a more time-free owner!
Link Surplus is the most recent recent website directory I've made, and it's getting 50-150 new links submitted per day.
Links Chief was my second attempt at creating a links directory (see below for my first attempt). It was pretty successful - within a month it had had over 1,200 links submitted to it, and it gained a strong alexa ranking (roughly 500,000) quickly.
I sold this site in late July 2007, and as such I no longer run Links Chief.
Stealth Web is a web proxy I created in April 2007. I still own and run it today. Its design was heavily modified from the default design of the web proxy script I used as I felt that a darker design suits a proxy better than a bright one!
I re-designed my church's website in 2003; making the site's structure easier to understand and the design more modern.
Track Your Company was my first links directory. As above, it quickly built up links and traffic - probably due to it targetting a specific niche (as apposed to being a general directory).
I sold TYC in march 2007 and it has since had a re-design (by the new owner).
Gamer's Place was the second proper website I created. I made it in 2003. It hosted game reviews for the PC, PS2 and GameCube, and also had forums.
