   All UUIDs are randomly generated but based on the same conditions. There are four versions to build a guild. Some use the MAC address of the computer. The last version uses a random number generator based on a pseudo algorithm.

   You can generate up to 10000 random identifiers once, but you can retry for how many times you want.
