Back in February, internet giant Google started making noises about a version of Gmail which website administrators could roll out for their own domain.

Over the past few days it has emerged that Google has been adding new functionality to the project, this week releasing Google Apps for Your Domain.

The new software suite, which is available free, includes customisable versions of Gmail, Google Talk and Google Calendar along with tools to brand them for a particular organisation.

The service also includes Google Page Creator for designing and publishing a website.

"There is no hardware or software required, and you can customise the user interfaces with your branding and colour scheme so they look and feel like your own," Google said.

The company added that it is still working on the service: "If you are from a larger business or university with more advanced needs for communications and sharing, please get in touch regarding premium versions of the service due out later this year."
