MMO is a abbreviation.
An abbreviation for the initials of the site/server owner for starters. A second meaning are the initials of the site owners and his wifes first names and last name.
There are of course other meanings which have nothing to do with this website, like massive multiplayer online [games] and maybe some others which I maybe even do not know.
That “to” behind the dot means nothing, it could be understood as a pointer like a swapped “to mmo”, but in the end that top level domain just was the best fitting one, expensive though.
The logo of this website is the abbreviation “mmo” reversed “omm” and written in elvish letters in the german writing type developed by Helmut W. Pesch.
