Like this UK forum I joined a year ago. I last visited it in August. A search on another post I did to see if it had been indexed yielded up this forum- along with an obvious mention of my name. I also had a backlink but without anchor text. A little more investigation and I discovered that I could put anchor text in my signature block, which I did promptly.
Best of all? The site is a PR6.
Continuing the SEO effort,
