What is a Guild?
A Guild is a group of players within the same organization, run by players themselves. It could be democratic, anarchistic, totalitarian, etc. Any player can join a guild for whatever reasons, and more simply a guild can just be a group of friends.
Each guild is supposed to provide mutual protection for all guild members, and a place where they can draw support and assistance from the other players (guildees, as they are often referred to).
How do I join a guild?
To join a guild you need to go at that guild profile, and click on «Request to join this guild».
Then your request must be accepted by a member of that guild with powers to accept new members.
Do I have to be a certain level to join a guild?
Whatever your level, there is no limitation when applying for a guild. Some guilds, however, will not accept members below a certain threshold.
You are unable to apply to join a guild if you are already in one.
Is there any limit of number of members in a guild?
The guilds are limited to 250 members.
What does the inactivity column mean at the guild page?
The numbers in the column represents the last time a player accessed that server.
example: an inactivity of 30 min they last accessed the game 30 minutes ago.
When defending a guild members base, will his defenses and/or command centers assist you in defending?
Base defences assist the base owner, but not members of the guild that player is in. The same applies to command centers.
How is a guild level calculated?
Guild Level = (Guild Economy x 100 + Guild Fleet + Avg. Guild Technology) ^ 0.25
(The ^ symbol denotes an exponent; ^.25 means to take the 4th root)
