We have a dedicated test server on which the site is hosted and even a dedicated development server which is currently hosted at www.auditioners.net:5150 Both these sites are likely to go down at random moments as we are not yet ready for real users.
Getting this far has been a struggle and we've had to learn a little more than we wanted to about Routers and Virtual Networks, etc. but we are live at last with Ubuntu 64bit server v10.4, MySQL, Glassfish and Liferay.
This latest version of Liferay (6.0x) is excellent, the "control panel" is a great innovation and the new social tools such the Wall and an updated Chat utility bring Facebook-like functionality quite easily into Liferay world. There's an annoying bug with the Blog and Message Board that requires an awkward work-around unfortunately but we got the workaround working so its "invisible" now.
Our next steps are to confirm our themes, community pages and default behaviour and then start to add our unique applications. Still a long way to go but it already looks like a proper site.
