I've now had a play with it - but i still feel its a waste of time so long as users wishing to access the
website hosting need to install software to do so. Also, they cannot email to the address created in the normal manner. I was able to send emails with my lovely new name from the dotWorlds control panel - but then you can do that with any email client - invent a name and insert it into the 'from' field etc. But you cannot reply to this email as it returns a failure to deliver notice.
Its not much use for a serious
website hosting - I see it useful for kids or similarly closed social group who will all download the software.
