Why my website address is something.magix.net/website ? Why not simply something.magix.net ? And why my online album has this address (something.magix.net)? It could be something.magix.net/album. It would be more logical and practical for me...
I guess the background might be that the Online Album service was there first, long before the website service. Ultimately, the naming convention for the Magix online services' URLs is somewhat arbitrary. It's just what it is. But obviously it could change, too.
