I have a .co.uk Wordpress blog which I've used as testing. It's an autoblog, and posts come in from SEOLinkVine, UAW and Free Traffic System.
I think it currently has just under 5,000 posts and is currently Google PR1 (home page only). The posts cover all sorts of topics.
It gets an average of between 15-20 visits per day.
It is up for renewal 11th May, it's an aged domain (registered since 2003).
I don't really want to renew it. Adsense income covers the cost of annual domain name registration.
If you're interested, PM me, or if I'm allowed to post the URL, I will here. I don't want anything for it, just take it for free.
