http://whois-it.info. I designed and coded a template and then coded in an open source ajax whois lookup tool. Here is a basic description: Whois-it is a free ajax powered whois domain tool. It allows you to instantly check whether a domain name is registered or not, and if not allows you to quickly and easily register it through the top domain registrars. I am currently SEO-ing it and after the PR update expect to see it for sale, haha. (unless of course someone buys it now *nudge* *nudge*). What do you think of the site, and are there any bugs?
When it says is taken doesn't specify the TLD that have been taken. Nice design, could have been better.
nice design, but missing the button for search... most people will get it, but you never know... good job with design and logo!
