Would it be possible for you to create a subdomain wiki.transportempire.com which you point on the wikiserver (aka your own server). I guess having the wiki on your own server is just a temporary soulution unless you got good backup hardware at home.
If that is possible, I have no idea how to it, it probably isn't without orudge's cooperation. My server isn't hosted at my home and as for backups, I already have a system in place for backing up MySQL databases, the only other thing is attachments, but there won't be many of them.
To setup a subdomain you should contact the domain registrar. http://www.joker.com
or whatever your domain registrar is. But if Owen is your domain registrar then I agree that you won't be able to do it without his cooperation.
And if it is not possible to create a subdomain you could go on and setup the wiki and add a wiki-link on the http://www.transportempire.com
website to the server which holds the wiki, using its IP. Since there is a link people does not need to remember the IP and it will only be temporary since Owen will come back won't he?
Is there any problems we me diverting the domain name back to my webspace so I can set up a wiki? Possibly to be reset to orudge's server when the time comes?
If you have the power to change where the domain points you'll likely also got the power to create subdomains.
