Yesterday, I learnt how to do subdomains. Basically, I can now set up things such as subdomain.alunmillard.co.uk. This is useful is I want to have different things pointing to different sites. http://tumblr.alunmillard.co.uk goes to this tumblr. http://www.alunmillard.co.uk current points to my tumblr, but could be changed to point at anything else.
