The title says it all and it is all so simple. Prefixes and suffixes GUARANTEE there is an endless supply of .coms. Put "The" in front of anything. Put "USA" at the end of anything. Or "global" or a "Location based" prefix or suffix. Add a dash. There are more .coms available than have been resgistered by a factor of 1000.
All I can do from here is add to my argument. But what for? The example speaks for itself and THOUSANDS and THOUSANDS of prefixes and suffixes are out there to use. com in short supply? NONSENSE!
