Obviously, the first step is thinking up the concept. What makes your guild different than other guilds? Why would I, the average, non-guilded player, wish to join your guild?
After that, you make a post in these here forums advertising your guild. You may also wish to start a guild website, as most people think guilds with websites look more proffessional. Never-ever advertise in-game, though! Never!
The following commands are useful for guild leaders:
/newguild
- Makes a new guild with name
/guildlevel - Renames the guild level
/guildinvite - Invites a player to join guild
/guildpromote - Promotes player to level
