Beside the guilds out there now recruting, How can you make a guild inside the game? What are the requirements? How many players can join a guild? Do they get their own building? Would you be able to easily create one in-game? If anybody knows a lot of info so far about this it would help some of us understand about guilds more, thanks.

Same as always. Click on the guild tab, set your guild and invite people.
I believe a guild can have up to 300 members. They gain, they need to earn their own castle. A player can enter in up to 5 players guids. I think that's it.
