This site has now moved to it’s own domain (garethlennox.com), rather than sitting in a subdirectory under another domain.
I managed to move it in the space of a couple of hours, without too many hassles. The main problem was that wordpress doesn’t like to have it’s main url changed from underneath it, so I had to get into the database and tweak some values. There is a good guide in the wordpress codex on how to do this.
Otherwise, marring some obscure file permission problems, it was very straight forward.
One other benefit of having my own domain is that I get to set the favicon for it, which is a smaller version of my logo. I used this handy tool to convert the favicon into a .ico format.
