It has come to my attention that the site I was using to store my code samples, http://stephen_griffin.members.winisp.net poses a problem for some users due to the underscore. Apparently some proxy server have problems handling sites with underscores. Sounds like a bug in the proxy server to me, but still I want people to be able to get to the samples.
So I've moved them all over to http://stephengriffin.members.winisp.net. Note that I've just dropped the underscore from the name. I should have all my articles updated with the new url before the day is over.
