The guild system of the Holy Spirit is the same as other game guild systems, featuring a guild-level system.
The levels range from one to ten, and each level increase in guild rank boosts the guild's attribute bonuses, guild warehouse, and guild welfare.
As for the number of members in the guild, it remains the same at each level. Some in the forums are asking why the developers wouldn't introduce something to increase the guild member capacity?
Jiang Qiao's response was... they were already working on it.
Currently, in the Holy Spirit, there are only seven level-ten guilds, which are the main guilds established by the seven clubs in China. Next, the level-nine guilds include player-formed guilds like the Dream Marriage Committee, which aren't managed by organizations.
There are many ways to increase a guild's level. Today, General Silver had summoned the presidents of the other five level-ten guilds in the Holy Spirit, all of whom were old acquaintances of General Silver.
