Gamesnet GUL: How to Play Ultima Online Shared ?

i've subscribe a Gul account ( gamesnet) , so now i can play into a ultima online shard hosted by GN.the question is: how can the GUL account be immediately active also in the shard?i can't recognize how it can works :Dcan anyone help me?(i hope i've explained my doubts in way u can understend my thought)

They probably share a database.

Yes....As Hercco stated GUL obviously uses databases that can interconnect if they tell them to so that any account could be activated fast.This is usefull so that the players (yourself) have a awesome time, without lag
